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

In a separate large bowl, whisk together flour, baking powder, and salt until evenly mixed.

Pour the dry mixture into the wet mixture, gently folding with a spatula until just combined.

Fold in chopped baby spinach and shredded mozzarella cheese into the dough.

Preheat oven to 400°F (200°C) while shaping the dough into bagel-like shapes.

Place the shaped flagels on a parchment-lined baking sheet and bake for 15-20 minutes, until golden brown.

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