Cook the Ground Beef. In a skillet over medium heat, cook the ground beef until browned and cooked through. Drain any excess grease.
Season the Beef. Add taco seasoning to the cooked ground beef, along with a splash of water. Stir to combine and simmer for a few minutes until heated through.
Assemble the Crunch Wraps. Place a flour tortilla on a flat surface. Layer the fillings in the center of the tortilla, starting with a scoop of seasoned ground beef, followed by a tostada shell, nacho cheese sauce, sour cream, shredded lettuce, diced tomatoes, and shredded cheddar cheese.
Fold and Cook. Fold the edges of the tortilla up and over the filling, creating a hexagonal shape. Place the Crunch Wrap, seam-side down, in a hot skillet or griddle. Cook for a few minutes on each side until golden brown and crispy.
Serve and Enjoy. Transfer the cooked Crunch Wrap Supreme to a serving plate. Slice in half and serve with your favorite dipping sauces, such as salsa, guacamole, or more sour cream.
