Brown the ground beef in a skillet over medium heat until fully cooked. Drain any excess fat.

Add the chopped onions and green peppers to the skillet and cook for an additional 4 minutes until softened.

Stir in the taco seasoning mix and cook according to the package instructions.

Prepare Cheese Mixture: In a separate bowl, mix together the Rotel and Nacho Cheese Sauce until well combined.

Lay the flour tortillas flat on a clean surface. Spread a generous spoonful of the Nacho Cheese mixture down the center of each tortilla.

Top the cheese mixture with a portion of the beef mixture. Add a dollop of sour cream, a sprinkle of diced onions and peppers, and a handful of crushed Doritos.

Fold in the sides of the tortillas, then roll them up tightly like a burrito.

Heat a clean skillet over medium heat. Place the wraps seam side down in the skillet and toast until golden and crispy, about 2-3 minutes per side.

Serve the wraps immediately with shredded lettuce and any additional toppings you prefer.
