Step 1

In a large shallow bowl or casserole dish, combine the marinade ingredients: lime juice, orange juice, soy sauce, olive oil, chopped cilantro, garlic, chili powder, cumin, and salt. Place Flank Steak into the marinade and turn several times to coat.

Step 2

Cover with plastic wrap and marinate in the refrigerator for at least 6 hours and preferably overnight. Turn the steak once while marinating.

Step 3

Preheat the grill to medium-high heat. Place marinated steak onto the hot grill and cook 3-5 minutes per side, flipping once or until the steak has reached the desired doneness (145˚F for medium-rare and 160˚F for medium doneness).

Step 4

Remove from the grill, tent with foil, and rest 5-10 minutes then thinly slice against the grain.
