Legend has it the pepperoni roll was a lunch option for coal miners in West Virginia since they didn’t need to be refrigerated and were easily packed for the midday meal. Since then, variations have sprung up to put cheese, peppers, or even different meats, but the classic remains sticks of pepperoni enclosed by a soft roll. Sliced pepperoni is not recommended. #larryskitchen
