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