01 - Heat olive oil in a large skillet over medium heat. Add ground beef, cumin, paprika, garlic powder, onion powder, salt, and pepper. Cook, breaking up the meat, until browned and cooked through, about 8–10 minutes. Drain excess fat if needed.
02 - In a small bowl, whisk together sour cream, mayonnaise, lime juice, salt, and pepper until smooth and well combined.
03 - Heat tortillas in a dry skillet or microwave until soft and pliable for easy rolling.
04 - Spread sauce onto the center of each tortilla. Layer with lettuce, tomato, onion, avocado, cooked beef, and shredded cheese.
05 - Fold in both sides of the tortilla and roll up tightly to enclose the filling. Slice in half diagonally if desired and serve immediately, or wrap in parchment paper for a portable lunch.
