Puff Pastry Pizza Bites

 1 sheet puff pastry dough, thawed but still chilled
3/4 cup marinara
1/3 cup ricotta cheese
1/2 cup shredded parmesan cheese
12 pepperoni slices, cut into smaller pieces

Preheat oven to 400.  Lightly grease a 12 cup muffin tin with nonstick cooking spray.  Roll out the puff pastry on a lightly floured surface to slightly enlarge the sheet.  Cut into 12 equal squares.  Gently press each puff pastry square into the muffin tin cups, letting the edges stick out slightly.  Add about 1 Tbsp of marinara sauce into each pastry cup.  Spoon a small dollop of ricotta cheese on top of marinara.  Sprinkle shredded parmesan cheese over the ricotta and marinara layers.  Add pepperoni pieces, distributing evenly across the cups.  Bake 15-18 minutes or until the puff pastry is golden brown and puffed.
