Preheat oven to 375°F (190°C) and line a baking sheet with parchment paper.
In a bowl, mix flour, baking powder, and salt.
Add cottage cheese, olive oil, chopped spinach, and mozzarella; mix gently until a sticky dough forms (don’t overmix).
Divide dough into 6 equal pieces.
Flatten each piece into a thick round (about ½-inch thick), then poke a hole in the center and widen slightly.
Place on the baking sheet. Brush with egg wash if using and sprinkle with seasoning (optional).
Bake 18–22 minutes, until golden and cooked through.
Cool 10 minutes, then slice and toast if desired.
