Preheat your oven to 375°F (190°C).

In a mixing bowl, combine whole wheat flour, low-fat cottage cheese, and the large egg. Add garlic powder, Italian seasoning, and salt. Mix until a soft, slightly sticky dough forms.

In a separate bowl, mix shredded mozzarella cheese with diced pepperoni or cooked sausage.

Roll out the dough on a floured surface to a rectangle about 1/4 inch thick. Cut into smaller rectangles, roughly 4x6 inches each. On one half, place a tablespoon of the cheese mixture and a tablespoon of your chosen filling.

Fold the other half of the dough over the filling and press the edges firmly to seal. Use a fork to crimp the edges. Place on a baking sheet lined with parchment paper.

Bake for 20-25 minutes, or until golden brown. Let cool slightly before serving with marinara sauce for dipping.
