Preheat your oven to 400°F and line a baking sheet with parchment paper to prevent sticking.
Divide the mozzarella cheese into small portions and arrange them into circular shapes on the prepared baking sheet. Ensure there is enough space between each circle to allow for even baking.
In a skillet over medium-high heat, cook the Italian sausage until it is fully browned and cooked through. Use a spoon to break the sausage into small crumbles as it cooks.
Place a spoonful of the cooked sausage and two slices of pepperoni onto each cheese circle. Adjust the amounts based on your preferred filling ratio.
Bake the cheese circles in the preheated oven for 8–10 minutes, or until the edges of the cheese begin to turn golden brown and crispy.
Remove the baking sheet from the oven and let the cheese circles cool for a few minutes. This helps them hold their shape better when rolled.
Carefully roll each cheese circle up over the filling while it is still warm. As they cool further, the rolls will crisp up for the perfect texture.
If desired, sprinkle the rolls with Italian seasoning for added flavor before serving.
