"I make these hearty fajitas all the time. Sometimes I like to add Portobello mushrooms to the onion and pepper mixture. The whole family loves them." —Amber Jensen, Whispering Pines, North Carolina
Instructions
1
In a small bowl, combine 1/2 cup oil, vinegar, oregano, sugar, chili powder, salt, garlic powder and pepper. Pour 1/2 cup marinade into a shallow dish. Add the beef and turn to coat. Cover; refrigerate for at least 8 hours or overnight. Cover and refrigerate remaining marinade.
2
Drain steak and discard marinade. Broil 4 in. from the heat for 5-7 minutes on each side or until meat reaches desired doneness (for medium-rare, a thermometer should read 135°; medium, 140°; medium-well, 145°), basting occasionally with reserved marinade. Let stand for 5 minutes before slicing.

Meanwhile, in a large skillet, saute onions and peppers in oil until tender. Serve on tortillas with beef and toppings.
