– flank steak or skirt steak – orange juice – lime juice – liquid aminos or soy sauce
Stir together the ingredients for the carne asada marinade in a bowl or measuring cup (orange juice, lime juice, vinegar, oil, cilantro, garlic, salt, and pepper) until well-combined.
Transfer the flank steak to a large (1-gallon) zip lock bag along with the marinade. Seal the bag tightly and gently move it around so that the full steak is exposed to the marinade.
For grilling, fire up your gas grill or charcoal grill until it reaches medium-high heat (450 to 500 degrees Fahrenheit).
