In a mixing bowl, combine cottage cheese, olive oil, and egg. Use a whisk or mixer to blend until smooth and creamy.

In a separate bowl, whisk together the all-purpose flour, baking powder, and salt until thoroughly mixed.

Gradually add the dry ingredients to the wet mixture, stirring gently with a spatula until a soft dough forms.

Gently fold in the finely chopped spinach and shredded mozzarella cheese until evenly distributed.

Lightly flour your hands and divide the dough into portions. Roll each into a ball and shape into flagels.

Preheat your oven to 400°F (200°C). Bake shaped flagels for approximately 15 minutes until golden brown.

Remove from the oven and let cool on a wire rack for a few minutes before serving.
