This is a cozy, savory “better-than-pizza” style dinner built from three simple parts: an oat-and-onion flatbread, juicy zucchini meat patties, and a creamy tuna-and-egg salad. Everything bakes at the same oven temperature, so it’s practical for busy weeknights and still feels like a full spread. The flatbread is naturally flour-light (oats do the work), and the patties bring plenty of protein. If you like easy sheet-pan meals with a few fresh toppings, you’ll love this. For another comforting, oven-friendly idea, take a look at this quick potato dinner as well.
Why This Recipe Is Helpful
- Uses one oven temperature (180°C / 356°F) to cook the flatbread and patties efficiently.
- Balanced plate: whole-grain oats + protein patties + creamy salad + fresh vegetables.
- Flexible: swap beef/chicken, adjust seasonings, and serve it family-style.
Best For
A satisfying family dinner when you want something different from sandwiches or regular pizza night, without complicated dough.
Be Careful If
This meal includes dairy (cheese, yogurt, sour cream) and is fairly filling; keep portions moderate if you’re watching calories.
Ingredients
Oat & Onion Flatbread
- 1 cup (90 g) oat flakes
- 1 medium onion, finely chopped (about 1 cup / 150 g)
- 2 tablespoons (30 ml) water
- 1/2 teaspoon salt, or to taste
- 1/3 cup (70 g) grated cheese (mozzarella, cheddar, or a blend)
- 1 teaspoon Italian herbs
- 1 tablespoon sesame seeds
Tuna Egg Salad
- 1 cucumber, sliced (about 1 1/2 cups / 200 g)
- 2 hard-boiled eggs, sliced
- 1/2 medium onion, finely chopped (use the remaining onion if you prefer)
- 1 tin tuna, drained (about 5 oz / 150 g)
- 3 1/2 tablespoons (50 g) sour cream
- 1 teaspoon whole grain mustard
- Black pepper, to taste
- Pinch of salt, optional (tuna can be salty)
Zucchini Meat Patties + Serving
- 1 medium zucchini, grated (about 1 1/2 cups / 200–250 g)
- 1 pound (500 g) ground meat (beef or chicken)
- 1 teaspoon dried garlic
- 2 tablespoons (30 g) plain yogurt
- 1 large egg
- 2/3 cup (100 g) grated cheese
- 3/4 teaspoon salt, or to taste
- Black pepper, to taste
- 1–2 tomatoes, sliced
Ingredient Notes
- Oat flakes: Quick oats work best; if using thick rolled oats, pulse briefly in a blender for better binding.
- Zucchini: Squeeze out excess water or the patties can steam and turn soft.
- Cheese: Any good-melting cheese works; sharper cheeses give more “pizza” flavor.
- Tuna: Oil- or water-packed both work—just drain well.
Kitchen Tools Needed
- 2 baking sheets
- Parchment paper
- Mixing bowls (2–3)
- Box grater
- Clean kitchen towel (for squeezing zucchini)
- Knife + cutting board
Step-by-Step Instructions
- Preheat the oven to 180°C (356°F). Line two baking sheets with parchment paper.
- Mix the flatbread dough: In a bowl, combine oat flakes, chopped onion, water, salt, 1/3 cup (70 g) grated cheese, Italian herbs, and sesame seeds. Stir until you have a thick, sticky mixture that holds together when pressed. If it feels dry, add 1 more tablespoon (15 ml) water.
- Shape the flatbread: Scrape onto one lined sheet. With damp hands or the back of a spoon, press into a thin round/oval about 1/4-inch (6–7 mm) thick. (Thinner edges get crispier.)
- Bake the flatbread for about 18–22 minutes, until golden and set. It should feel firm at the center and smell toasty.
- Prep the zucchini for patties: Grate zucchini, then wrap in a towel and squeeze hard over the sink to remove as much liquid as possible.
- Mix the patties: In a bowl, combine squeezed zucchini, ground meat, dried garlic, yogurt, egg, 2/3 cup (100 g) grated cheese, salt, and pepper. Mix until evenly combined (don’t overmix or they can get dense).
- Form and bake: Shape into 10–12 small patties and place on the second lined sheet with space between them. Bake at 180°C (356°F) for 18–22 minutes, until cooked through.
- Doneness cue: browned edges, juices run clear, and the center is no longer pink (aim for 165°F / 74°C internal for chicken).
- Make the tuna egg salad: In a separate bowl, mix cucumber, sliced eggs, chopped onion, drained tuna, sour cream, and mustard. Season with pepper and a pinch of salt if needed.
- Serve: Slice the flatbread, plate with zucchini patties, add sliced tomatoes, and spoon on the tuna egg salad.
Pro Tips
- Press the flatbread thin and even so it bakes through; thick centers can stay soft.
- For browner patties, place the tray on the upper-middle rack and avoid overcrowding.
- If your tuna salad seems watery, drain tuna very well and add cucumber right before serving.
- Let the flatbread rest 5 minutes before slicing so it sets cleanly.
Lighter Swaps
- Use lean ground chicken and reduced-fat cheese in the patties.
- Swap sour cream for plain Greek yogurt in the salad.
- Serve a bigger portion of cucumber/tomato and a smaller portion of flatbread if you want a lighter plate.
Common Mistakes
- Not squeezing the zucchini enough (leads to soft, wet patties).
- Making the flatbread too thick (it won’t crisp or set properly).
- Overbaking the patties until dry—pull them when just cooked through.
Serving Suggestions
Serve family-style on a big board: flatbread wedges, patties, tomatoes, and a bowl of tuna salad for scooping and topping.
Storage Instructions
Store flatbread, patties, and salad separately in airtight containers for up to 3 days in the fridge.
Reheating Tips
Reheat flatbread and patties in a 350°F / 175°C oven for 8–10 minutes (or air fryer) to bring back some crispness; keep the tuna salad cold.

Frequently Asked Questions
Can I make the flatbread with quick oats instead of oat flakes?
Yes. Quick oats work very well and bind easily; if your mixture feels loose, let it sit 3–5 minutes to thicken before shaping.
Can I pan-fry the patties instead of baking?
You can, but baking keeps things simpler since the oven is already on. If pan-frying, use medium heat and cook until fully done, turning gently.
Is the tuna salad necessary?
No. It’s delicious, but you can skip it and serve the flatbread and patties with extra cucumber and tomato, or any simple side salad you like.
Conclusion
This dinner gives you that “pizza night” satisfaction with an easy oat flatbread, hearty zucchini patties, and a cool creamy salad on the side. It’s practical, filling, and flexible with whatever cheese or ground meat you have. Once you try it, it’s the kind of meal you’ll repeat on busy weeks.
