Separate crescent rolls in triangles. Flatten each triangle and slice into 3 small triangles. Dice pepperoni into very small pieces and add cream cheese. Mix well. Put a small spoonful of cream cheese/pepperoni in the middle of each small triangle. Pinch all sides around filling, rolling into a ball. Place balls onto cookie sheet and bake 10-13 minutes at 375.
You can add shredded mozzarella cheese with the filling to make them gooey.
