Step 1

In a small bowl, stir together the oil, lime juice, seasoning mix, cumin, and pepper until well-combined. Pour mixture over steak, evenly coating both sides of meat; chill covered for at least 1 hour (overnight is best).

Step 2

Preheat the grill or broiler. Remove the steak from marinade; discard any remaining marinade.

Step 3

Grill the steak for 7 to 9 minutes on each side for medium doneness. Let the steak rest covered for 5 minutes before slicing into thick strips.

Step 4

Serve the steak with tortillas, guacamole, sour cream, picante sauce, along with lime wedges.
