Seared Beef Fajitas

Combine all marinade ingredients. Place the marinade in a large resealable plastic storage bag. Add the steak, reseal the bag and turn to coat the steak. Marinade at room temperature for 1 hour, or longer in the refrigerator, turning the bag ocassionally. Prior to cooking the meat, remove most of the marinade and sprinkle the steak with salt.

Wrap tortillas tightly in foil. Heat in a 350ºF / 180ºC oven for about 10 minutes or until heated through.

Heat a large cast iron pan or skillet over high heat for 1 to 2 minutes. Add the oil to the pan and heat for 1 minute. Add the steak, browning on each side for 3 to 4 minutes, or to desired doneness. Remove from pan, tent loosely with foil, for 5 minutes.

While the steak is resting, saute the vegetables. Add a little more oil to the pan if necessary, then add the onions and bell peppers. Sear for 1 minute before stirring, then stir every 90 seconds or so until tender crisp, about 5 to 6 minutes.
