Preheat your oven to 375°F (190°C).
Open the tube of refrigerated biscuits and separate them into individual pieces.
Flatten each biscuit and place a piece of mozzarella cheese and a couple of pepperoni slices in the center. Fold over and seal.
In a mixing bowl, combine olive oil, garlic powder, and Italian seasoning. Mix well.
Roll each biscuit in the olive oil mixture, ensuring they are well coated.
Place the coated bombs on a baking sheet lined with parchment paper and sprinkle with grated parmesan cheese.
Bake for 12-15 minutes until golden brown and cheese is bubbly.
Let cool for a few minutes and serve warm with marinara sauce.
