Cook the ground beef in a skillet over medium heat until browned. Drain excess fat.
Add taco seasoning to the beef and cook according to the packet instructions.
Warm the flour tortillas in the microwave for about 20 seconds to make them pliable.
Place a flour tortilla on a flat surface. Spread a layer of nacho cheese sauce in the center.
Add a scoop of the seasoned beef on top of the cheese sauce.
Place a corn tortilla on top of the beef. Spread a layer of sour cream over the corn tortilla.
Add shredded lettuce, diced tomatoes, and shredded cheese on top of the sour cream.
Fold the edges of the flour tortilla towards the center to create a hexagon shape, enclosing the fillings.
Heat a skillet over medium heat. Place the folded Crunchwrap seam-side down in the skillet and cook until golden brown, about 2-3 minutes per side.
Repeat with the remaining tortillas and fillings. Serve hot.
