Preheat oven to 375 and grease a regular muffin pan
Cut biscuits into small, even pieces
In a bowl, mix biscuit pieces with mozzarella, pepperoni, marinara, olive oil, egg, and seasoning until evenly coated
Scoop into muffin pan, filling about 3/4 full and gently press to hold together (don’t pack tightly)
Top with a parmesan
Bake 16 to 18 minutes, until golden on top and set in the center
Let cool slightly before removing so they hold together
