Preheat oven to 4oo F. Line a baking sheet with silicone baking mat or lightly grease with non-stick cooking spray.
Roll out the biscuit dough until flattened and add spoonful of pizza sauce, then add a few slices of pepperoni, chopped bell peppers (or other favorite pizza toppings) and a hefty pinchful of shredded cheese.
Fold the biscuit dough around the filling ingredients and pinch closed. Repeat until 8 calzones are made.
Bake in the preheated oven for 12 to 15 minutes, or until dough is cooked through and begins to golden on top.
