01 - Heat olive oil in a large skillet over medium-high heat. Add the diced red onion and sauté for 2 minutes until softened and translucent.
02 - Add ground beef to the skillet and cook, breaking it apart with a spoon or spatula, for 5 to 7 minutes until fully browned. Drain excess fat if needed.
03 - Stir in chili powder, ground cumin, smoked paprika, garlic powder, onion powder, salt, and black pepper. Mix thoroughly and cook for 2 additional minutes to bloom the spices. Remove from heat.
04 - Soften the large flour tortillas by warming them in a microwave for 15 seconds or heating briefly in a dry skillet until pliable.
05 - Lay a large tortilla flat. Spread 2 tablespoons of nacho cheese sauce in the center. Layer on the seasoned beef, shredded cheddar cheese, a tostada shell or a few tortilla chips, salsa, shredded lettuce, diced tomato, sliced jalapeño, and sour cream.
06 - If using, place a small taco-size tortilla on top of the filling to help seal. Fold the edges of the large tortilla up and over the center, working your way around to form a hexagonal shape and pressing firmly to close.
07 - Heat a clean skillet over medium heat. Place the folded wrap seam-side down and toast for 2 to 3 minutes until golden and crispy. Flip and toast the other side for an additional 2 minutes.
08 - Slice each wrap in half and serve immediately while hot.
