Ensure all ingredients are prepared before starting the cooking process. Shred cheese, dice tomatoes, shred lettuce, and set aside your tortillas, tostadas, and sour cream (or greek yogurt). Prepare your area for assembly.
Heat a large non-stick pan on medium-high heat and gently spray with non-stick spray, or prepare a flat panini press (no ridges) with non-stick spray and heat.
Heat up a single grande tortilla (for 5-10 second in microwave, or on the heated pan on the stove) and lay it flat on your assembly surface.
Layer a large spoonful of meat, then a tostada, then lettuce, diced tomatoes, and another small spoonful of meat. Smear a large dollop of sour cream and then top with a healthy portion of cheddar cheese.
Fold the soft tortilla around, folding the tortilla in toward the center on one side. Fold a newly formed corner in, and rotate repeating to make 6 total folds so the whole thing is covered. Ideally, there's no open hole, but the cheese is on top to melt and help form a protective seal on top.
If you have a flat panini press go ahead and lay the crunchwrap between the plates and cook for 3-5 minutes or until toasted on both sides.If using the stovetop, place crunchwrap folded side down onto the hot pan. Cook for 2-4 minutes on each side until toasted and browned to desired doneness. Flipping may be messy if there's a hole or the tortilla comes undone! Remove to plate and repeat for remaining crunchwraps.
