Preheat oven to 375°F.
Separate the crescent rolls and add a few pepperoni and half a string cheese to the wide end of the crescent roll. Roll, tucking in the ends, and place on a baking sheet seam-side down. Repeat for all crescent rolls.
Bake for about 12 minutes.
Once fresh from the oven, brush with melted butter and sprinkle with pizza seasoning. Enjoy warm.
