In a mixing bowl, combine the cottage cheese, olive oil, and egg. Blend until smooth and creamy, about 2-3 minutes.

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

Gradually add the dry ingredient mixture to the wet mixture and stir until just combined, about 1-2 minutes.

Fold in the finely chopped baby spinach and shredded mozzarella cheese with a gentle hand.

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

Place each shaped flagel on a parchment-lined baking sheet and bake for about 15 minutes until golden brown.

Transfer the flagels to a wire rack to cool for 5-10 minutes.
