Preheat oven to 350. Slice string in four quarters. You should have 8 pieces total after slicing.
Open crescent rolls. Unroll and separate at perforations. Place two slices of pepperoni on top the crescent. Then place one string cheese quarter on the pepperoni. Sprinkle with italian seasoning and red pepper flakes to your liking. Roll wide end to pointy end. Repeat for all crescents. Place on a foil lined cookie sheet.
Bake for 12-15 minutes or until crescents are golden brown. (this would probably be good with some garlic butter on top before baking)
