Preheat your oven to 375°F (190°C).

In a large mixing bowl, combine the whole wheat flour, baking powder, and salt. Whisk together.

In another bowl, mix together the cottage cheese, Greek yogurt, egg, and fresh spinach until smooth.

Pour the wet mixture into the dry ingredients and fold gently until just combined.

Lightly flour a surface, turn out the dough, and shape it into bagel forms.

Place the shaped flagels on a parchment-lined baking sheet; optionally brush with olive oil or egg wash.

Bake for 20-25 minutes until lightly browned on top.

Cool on the baking sheet for a few minutes, then serve warm with toppings.
