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

In a separate bowl, whisk together flour, baking powder, and salt until uniform in color.

Gradually add the dry mixture to the wet ingredients, stirring gently until just combined, about 1-2 minutes.

Gently fold in the chopped spinach and mozzarella cheese, mixing until evenly distributed.

Dust hands with flour, divide the dough, and shape into bagel-like forms, placing them on a lined baking sheet.

Preheat oven to 400°F (200°C) and bake for about 15 minutes until golden brown.

Remove from oven, cool on a wire rack for a few minutes before slicing or enjoying as is.
