Create the marinade by mixing 1 tablespoon of olive oil, lime juice, garlic, cilantro, cumin, salt, and pepper into a bowl.


Score steak with a sharp knife, on both sides. (Make diagonal cuts 1 ½ inches apart.)


Place the steak into a large resealable plastic bag and pour the marinade over the meat. Let steak marinade for at least 4 hours in the fridge (preferably overnight).


Once steak has been marinated, heat a tablespoon of olive oil in a non-stick pan and add sliced bell peppers & onions. Sprinkle with salt, pepper, oregano, and cumin. Sauté until onions and peppers are tender and slightly browned. Squeeze in juice of half a lime and remove from heat.


Let the flank steak sit at room temperature for at least 30 mins before you start to grill.


Grill steak to desired doneness, then slice thinly across the grain.


Mix grilled flank steak strips into sautéed peppers and onions and serve.
