Start by gathering all your ingredients: flour tortillas, pizza sauce, mozzarella cheese, and beef pepperoni. Premeasure everything to streamline the cooking process.

Take each tortilla and spread pizza sauce across the surface, leaving a small border around the edges.

Layer mozzarella cheese and beef pepperoni over the sauce, distributing them evenly.

Roll each tortilla tightly and slice into bite-sized pieces, about 1 to 2 inches wide.

Preheat a skillet over medium heat, add oil or butter, then place roll-ups seam-side down and cook until golden brown.

Remove from skillet once cooked, let cool for a moment, and serve with marinara sauce for dipping.
