Preheat your oven to 180 degrees Celsius (350 degrees Fahrenheit). Line a baking tray with parchment paper.

In a large bowl, whisk together the Greek yogurt and eggs until smooth and well combined.

Stir in almond flour (if using), psyllium husk, salt, and baking powder until the mixture forms a thick batter.

Add the flax seeds and mixed seeds, mixing until a firm dough comes together.

Shape the dough into a round or oval loaf and place it on the lined baking tray.

Sprinkle additional seeds over the top of the loaf and press them down gently to ensure they stick.

Bake for 60 minutes or until the bread turns golden and sounds hollow when tapped.

Let the loaf cool on a wire rack before slicing it into even pieces.
