Set one of the racks in the middle of the oven and preheat it to 400 degrees F. Additionally, use parchment paper to line a sheet pan.
Combine the Greek yogurt and protein flour in a mixing basin and stir to combine. Add extra yogurt if the dough is too thick. Increase the flour if the dough is too thin. Form the dough into a smooth ball using your hands.
Roll the dough with a rolling pin to create a thin, round pizza shape after dusting it with flour. Add more flour if it becomes sticky. Gently place the dough on a baking sheet-lined oven pan.
Leaving a thin border around the edges, cover the crust with the pizza sauce.
Top with bell pepper, red onion, turkey pepperoni, and shredded chicken (or your preferred toppings). Add mozzarella cheese on top.
The pizza should be baked for 15 to 20 minutes, or until the cheese has melted and the crust is brown. You might need to bake it for a bit longer if there are a lot of toppings. Keep an eye on it and broil for 1-2 minutes at the end for an extra cheesy crisp!
After 5 minutes of cooling, cut into slices and serve!
