Heat oven to 375°F (190°C) and grease a 9x13-inch baking dish.
Brown ground beef in a skillet over medium-high heat, breaking it apart. Drain excess grease.
Add onion, bell pepper, and chopped pepperoni. Cook 5–7 minutes until softened.
Stir in garlic; cook 2 minutes, then remove from heat.
Stir in 1/3 cup pizza sauce, Italian seasoning, ricotta, mozzarella, and crumbled bacon until creamy.
Spoon filling down each tortilla, roll tightly, and place seam-side down in the dish.
Top with remaining pizza sauce, mozzarella, pepperoni slices, and bacon.
Bake 20–25 minutes until cheese melts and edges are golden.
Cool 5 minutes before slicing and serving.
