Preheat oven to 400 degrees.

Line a cookie sheet with a baking mat or parchment paper.

Now lay slices of cheese on the baking mat and add your pepperoni, black olives, and sausage crumbles.

Place in the oven for 15 minutes or until cheese slices start to slightly brown around the edges.

Remove from the oven and allow the cheese to slightly cool. Allow the slices to cool slightly.

Roll and serve with marinara sauce.

Enjoy!
