Add cottage cheese, eggs, Parmesan cheese, and Italian seasoning to a blender. Blend for about 30 seconds, or until smooth.
Add parchment paper to a baking sheet and spray the parchment paper with olive oil spray.
Slowly pour the blended cottage cheese mixture onto the prepared parchment paper.
Bake at 350°F for 30–35 minutes, or until the flatbread is set and lightly golden.
Add pizza sauce, mozzarella cheese, and pepperoni over the baked flatbread.
Bake for another 5–10 minutes, or until the cheese is melted and the pepperoni is heated through.
Slice, serve, and enjoy.
