Instructions: In a medium bowl, combine margarita mix, vegetable oil, cilantro, garlic, cumin, salt, and pepper; mix well. Reserve 3 tablespoons of the marinade and set aside. Place steak and remaining marinade in a resealable plastic storage bag, turning to coat. Marinate in the refrigerator for 2 to 4 hours, turning occasionally.

Meanwhile, combine avocado, tomato, onion, and reserved 3 tablespoons of marinade; mix well. Cover and chill until steak has finished marinating. Preheat the grill to medium-high heat.

Remove steak from the marinade, discarding excess marinade. Grill steak for 8 to 9 minutes per side for medium doneness, or until desired doneness beyond that. Slice steak across the grain and serve with the chilled avocado salsa.
