In a skillet, cook the beef over medium-high heat.
Add the taco seasoning and cook according to the package directions.
Place the flour tortillas out and spread ~1-2 tablespoon of the nacho cheese about the size of the tostada.
Sprinkle with ~1 tablespoon of cheese and then top with a tostada.
Spread a thin layer of sour cream on top of the tostada.
Top the sour cream with ⅓ cup of the taco meat.
Sprinkle shredded lettuce, diced tomatoes and more shredded cheese on top of the beef.
Using one of the extra flour tortillas, cut a circle about the size of a tostada to place on top of the shredded cheese.
Next, starting at the bottom, fold up the large tortilla, working around the tortilla to creat the Crunchwrap supreme.
Heat a skillet over medium heat and drizzle with a little oil.
Add the Crunchwrap, seam side down. Cook about 3-4 minutes on each side until golden brown and the cheese is melted.
Cut in half. Serve and enjoy!
