Instructions
Preheat the oven to 400 degrees F (200 degrees C). Using kitchen shears, snip four 1/2-inch cuts around the edges of each large pepperoni slice, leaving the center uncut.
In a 24-count mini muffin pan, press each pepperoni down, followed by a crouton, a spoonful of pizza sauce, cheese, and mini pepperonis.
Bake in the preheated oven until cheese melts, about 10 minutes.
