In a medium skillet, heat 1 tablespoon olive oil over medium heat until hot. Add in ½ pound Italian sausage, 3 cloves garlic, ½ large green pepper, and 1 small onion. Cook until softened, about 6 minutes.
Add in 4 ounces mushrooms and ½ cup diced pepperoni, and cook until the mushrooms have just released their water, about 2 minutes. Stir in 2 cups marinara sauce, reduce heat, and simmer until thickened, about 10 minutes.
Remove from heat, stir in 1 cup shredded mozzarella cheese, and set aside. Preheat oven to 375°.
Spray a baking sheet with Cooking spray. Arrange three wonton wrappers along the bottom edge of the sheet. Spoon about 1 tablespoon of filling into the middle of each wrapper. Using a finger dipped in water, run along the edge of each wrapper and then fold wrapper in half and press down to seal.
Continue until baking sheet is filled with pizza rolls (spaced about 1″ apart). Spray tops with cooking spray and bake in preheated oven for 12-15 minutes, or until rolls are golden and crispy. Repeat process with remaining wraps and filling.
If pizza rolls are greasy, blot them with paper towels before serving. Let cool 5-10 minutes before serving (filling will be hot).

Notes
Veggie-option: leave out the Italian sausage and the pepperoni when making the filling. You may need to add more olive oil to keep the mushroom mixture form sticking while cooking.
These reheat great in the air fryer! Six minutes at 390°F worked well, but you might need to experiment with your air fryer to find the right time and temp.
