Preheat your oven to 400 °F (about 200 °C).
In an oven-safe bowl, combine the blended cottage cheese, marinara sauce, almond (or gluten-free) flour, chopped peppers, onions, olives, oregano (or Italian seasoning), salt, and pepper. Stir until evenly mixed.
Smooth the mixture level in the bowl.
Sprinkle the shredded mozzarella evenly on top. Then arrange the pepperoni slices over the cheese layer.
Bake for about 5–7 minutes — or until the cheese is melted, bubbly, and the pepperoni starts to crisp. If you prefer a thicker, slightly firmer texture, you can bake a bit longer.
Once baked, optionally garnish with fresh basil or parsley and a little grated Parmesan, if you like. Serve warm.
