Putting It All Together
Cut each roll in half, lengthwise, and place of a baking sheet.
Slice pepperoni stixs into small chunks, I cut each stix into 4 long pieces and then cut into desired size chunks, set aside.
Spoon sauce over each roll, cover with mozzarella, add a layer pepperonis, then pepperoni chunks, more cheese, more chunks of pepperonis and finally top with diced jalapenos.
Pop em' in the oven for 20-25 minutes or until cheese is starting to brown and bread is crisp.
