Beef Fajitas with Cilantro Sauce

Directions

1. In a shallow dish, combine 3 tablespoons lime juice, 2 tablespoons oil, thyme and hot pepper sauce. Add the beef and turn to coat. Cover; refrigerate for at least 2 hours.
2. For sauce, place the yogurt, cilantro, jalapeno and remaining lime juice in a blender; cover and process until smooth. Transfer to a small bowl; refrigerate until serving. Brush green peppers and onions with remaining oil; set aside.
3. Drain and discard marinade. Grill beef, uncovered, over medium-hot heat for 6-7 minutes on each side or until meat reaches desired doneness (for medium-rare, a thermometer should read 135°; medium, 140°; medium-well, 145°). Let stand for 10 minutes before slicing.
4. Meanwhile, grill green peppers and onions, uncovered, over medium-hot heat for 5 minutes on each side or until crisp-tender. Cut into strips; spoon onto tortillas. Top with sliced beef. Serve with cilantro sauce. Garnish with lettuce, tomatoes and olives if desired. Fold in sides.
