In a spacious mixing bowl, combine cottage cheese, olive oil, and egg. Blend until smooth and creamy.

In a separate bowl, sift together all-purpose flour, baking powder, and salt. Whisk until well combined.

Gradually add the dry mixture into the wet ingredients, stirring with a spatula until just combined.

Gently fold in finely chopped baby spinach and shredded mozzarella cheese into the dough.

Preheat your oven to 400°F (200°C). Lightly flour your hands and shape the dough into bagel-like shapes.

Transfer the shaped flagels into the preheated oven and bake for approximately 15 minutes.

Remove from the oven and let them cool slightly on a wire rack for about 5 minutes.
