Preheat oven to 425°F. Line a baking sheet and brush it with olive oil.
Stir melted butter with garlic, parsley, salt, red pepper flakes, and Italian seasoning.
Cut the dough into 24 pieces. Flatten each piece into a small disk.
Combine mozzarella and Parmesan in a bowl for the filling.
Spoon some cheese into each disk. Pinch edges to seal into a ball.
Toss dough balls in the garlic butter until lightly coated.
Arrange seam side down on the sheet. Brush with extra butter and sprinkle any leftover cheese.
Bake 12–15 minutes, until golden and the cheese is bubbly.
Cool 2 minutes. Serve warm; add marinara for dipping if you like.
