In a large skillet, cook the ground beef over medium heat until browned.
Add the diced onion and bell pepper to the skillet and cook until softened.
Stir in the taco seasoning and nacho cheese sauce, mixing until well combined.
Preheat a separate skillet over medium heat and warm up the flour tortillas one at a time.
Divide the beef mixture evenly among the warmed tortillas, then top with shredded cheddar cheese.
Roll up the tortillas to form wraps, tucking in the sides as you go.
Return the wraps to the skillet and cook until the cheese is melted and the tortillas are golden brown.
Serve the wraps with your favorite toppings and enjoy!
