Cook the Meat: In a skillet, brown the ground beef over medium-high heat. Stir in the taco seasoning (and a dash of onion powder, if desired) and let it simmer until fully cooked.
Build the Base: Lay a large, burrito-sized flour tortilla flat on your workspace. Spoon a scoop of the seasoned beef directly into the center and top it with a layer of queso dip.
Add the Crunch: Gently press a crunchy tostada shell right on top of the beef and queso. (If you are adding refried beans, spread them onto the tostada shell first).
Layer the "Supreme" Toppings: Spread a generous layer of sour cream over the tostada. Top with thinly sliced lettuce, diced tomatoes, and a heavy sprinkle of shredded cheese.
Add the Lid: Place a small soft tortilla (or just use another large one, keeping it simple!) directly on top of the veggies and cheese to act as your center seal.
Fold It Up: Tightly fold the edges of the large bottom tortilla up and over the center "lid," creating a pleated, hexagonal package. Hold it tightly so it doesn't unfold.
Seal and Toast: Heat a lightly greased skillet over medium heat. Carefully place the Crunchwrap into the hot skillet seam-side down. Note: Cooking it seam-side down first is the most crucial step, as it glues the chaotic folds together into a sturdy crust!
Flip and Finish: Cook for a few minutes until the bottom is perfectly golden-brown and sealed. Carefully flip and toast the other side.
Rest and Serve: Transfer the finished Crunchwrap to a cutting board and wait 60 seconds to let the cheese set up. Slice it diagonally down the middle and serve immediately!
