  1. Sliver one-quarter of the onion and set aside. Chop the rest of the onion. Mix it in a bowl with the vinegar, capers, oregano, and garlic. Combine 1/4 cup of this mixture with the slivered onions and set aside.
  2. Sprinkle both sides of the steak with the salt and pepper; prick well with a fork. In a large zip-top food-storage bag, combine the steak with the remaining onion mixture. Marinate for 1 hour or overnight.
  3. Heat the grill or the broiler, positioning the oven broiler rack so that the meat on the rack in the pan is 4 inches from the heat source. Remove the meat from the marinade, and place on the grill over direct heat or on an oven rack set in the broiler pan. Discard the marinade. Grill or broil for 4 to 5 minutes per side for medium-rare. Let stand for 5 minutes before slicing.
  4. Place the meat on a platter and pour the reserved onion mixture over the steak.

This recipe was easy and delicious. I left out the capers, marinated about 7 hours and cooked it on my Forman for 5 minutes(med-rare to med). The flank steak melted in my mouth.

This was simple and delicious. I used a fork to poke some holes in the steak (I actually used london broil) and then poured the marinade over, making sure it was thoroughly coated, then marinat...

Oh my. I make my flank steak with this all the time now. It is WONDERFUL!!!

I thought this was alright. Instead of using flank steak, I made the mistake of using a good cut of Beef Top Sirlon. The marinade did not make enough to endulged the entire steaks. I also did no...
