In a large skillet over medium heat, add the ground beef. Cook for about 6-8 minutes, breaking the meat apart with a spatula, until fully browned. Drain any excess fat from the skillet.
Pour the taco seasoning and 1/2 cup of water into the skillet with the beef. Stir well to combine all ingredients. Allow the mixture to simmer uncovered for about 5 minutes, or until it thickens. Taste and adjust seasoning with salt and pepper, if desired.
In a large mixing bowl, combine the cooked white rice, beef mixture, shredded cheddar cheese, and nacho cheese sauce. Stir thoroughly until all ingredients are evenly distributed.
To prepare the tortillas, warm them in a dry skillet over low heat for about 10-15 seconds on each side or microwave them for about 15-20 seconds until they become soft and pliable.
Take a warmed tortilla and lay it flat on a clean surface. Spoon a generous portion of the beef and rice mixture along the center of the tortilla.
Top the mixture with a dollop of sour cream, a sprinkle of diced tomatoes, sliced green onions, and chopped cilantro (if desired).
Carefully fold the sides of the tortilla inwards, then roll it up tightly from the bottom, ensuring all fillings are secure inside the wrap.
For a deliciously crispy finish, heat a skillet over medium heat. Place the burritos seam-side down in the skillet and cook for 2-3 minutes until golden brown and crispy. Carefully flip the burritos and cook for an additional 2-3 minutes on the other side.
Notes
Serve with extra nacho cheese for dipping and garnish with cilantro.
