1/4 cup lime juice
2 Tbsp olive oil
4 cloves garlic, crushed
2 tsp soy sauce
1 tsp salt
1/2 tsp liquid smoke
1/2 tsp cayenne pepper
1/4 tsp black pepper
1 lb flank steak OR boneless, skinless chicken breast
1 large white onion, sliced in thin rings
1 red bell pepper (green or yellow works), seeded and sliced in thin rings
Combine the lime juice, oil, garlic, soy sauce, salt, liquid smoke, peppers, and either the flank steak OR the chicken in a container, cover, and refrigerate at least 2 hours or overnight.
Save the leftover marinade liquid and grill the meat over medium flame 4-5 minutes on each side. Let rest for at least 5 minutes. Cut meat into thin strips. Set aside and keep warm.
Soak peppers and onions in leftover marinade for a couple minutes before cooking. Grill the onions and peppers for about 3 minutes a side.
