Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.
In a mixing bowl, melt mozzarella and cream cheese together, then mix in almond flour, whey protein isolate, baking powder, and an egg to form the dough.
Place the dough on a silicone mat, roll it out to about 1/4-inch thick.
Spread pizza sauce evenly, then layer with mozzarella cheese, turkey pepperoni, and bell peppers. Season with garlic powder, Italian seasoning, salt, and pepper.
Roll the dough into a tight log and slice it into 1-inch pieces.
Place the rolls on the prepared baking sheet and bake for 20-25 minutes until golden brown.
Notes
For best results, store any leftovers in the fridge and reheat in the oven to retain their crispiness.
