I made these last night and they are WONDERFUL!! I went to the Weight Watchers website and I figured these as 6 points per serving (Serves 4 - two fajitas each). This does not include, cheese, sour cream or any sides.
To prepare marinade, combine first 10 ingredients in a large bowl; set aside.
To prepare fajitas, trim fat from steak and cut against the grain into strips. Combine 1 1/2 cups marinade and steak in a large zip-top plastic bag. Seal and marinate in refrigerator 4 hours or overnight, turning occasionally.
Combine remaining marinade, bell peppers, and onion in a zip-top plastic bag. Seal and marinate in refrigerator for 4 hours or overnight, turning occasionally.
Remove steak from bag; discard marinade.
Remove vegetables from bag; reserve marinade. Place reserved marinade in a small saucepan; set aside.
Place steak and vegetables on skewers (soak them in water for a bit so they do not burn)cook until desired degree of doneness.
Wrap tortillas in a damp paper towel and microwave until soft.
Bring reserved marinade to a boil.
Take the steak and vegetables off the skewers and onto a serving platter; drizzle with reserved marinade.
Serve the meat and veggies with the flour tortillas and let people make their own fajitas. Pass chopped cilantro.
