In a mixing bowl, combine 1 cup of cottage cheese, 2 tablespoons of olive oil, and 1 large egg. Blend these ingredients until smooth and creamy, using a hand mixer or whisk.

In a separate bowl, whisk together 1 ½ cups of all-purpose flour, 1 tablespoon of baking powder, and ½ teaspoon of salt until well combined.

Gradually add the dry mixture to the wet ingredients, stirring gently until just combined.

Fold in 1 cup of finely chopped baby spinach and ½ cup of shredded mozzarella cheese to the dough.

Turn the dough onto a lightly floured surface, divide into equal portions, and shape each piece into a bagel-like form.

Preheat your oven to 400°F (200°C) and bake the flagels for about 15 minutes.

Remove the flagels from the oven and let them cool on a wire rack.
