Preheat the oven to 375 degrees. Unroll the crescent roll dough and spread the marinara sauce in an even layer over the top of the dough.

Sprinkle the shredded cheese over the top of the sauce.

Add the pepperoni to the top of the cheese.

Roll the dough up into a long log, then use a sharp knife to cut the log into 10 1-inch slices.

Place the slices on a baking sheet lined with parchment paper. Bake the crescents for 10 to 12 minutes, until the dough is golden brown. Serve immediately.
