Stir in chopped garlic and cook for an additional 1 to 2 minutes until fragrant.
Add 1/3 cup pizza sauce, Italian seasoning, ricotta, 1 cup shredded mozzarella, and 1/3 cup crumbled bacon to the skillet. Mix until combined and heated through.
Distribute the beef mixture evenly down the center of each flour tortilla, then roll tightly.
Place each filled tortilla seam-side down on a greased baking sheet. Pour 2 cups pizza sauce over the enchiladas.
Sprinkle 2 1/2 cups shredded mozzarella, desired pepperoni slices, and 1/4 cup crumbled bacon evenly over the top.
Bake for 20 to 25 minutes until the cheese is fully melted and golden brown.
