1 flank steak- sometimes certain grocery stores don't have it out. If you don't see it ask the butcher and they can usually get you one.
1/2 cup oil
1/2 cup fresh lemon (I usually just squeeze one lemon into the marinade with a fork)
1/2 cup soy sauce
2 cloves fresh garlic, minced
salt to taste
put all of the ingredients into either a pyrex dish or a ziplock bag. Let marinate for at least 2 hours. I usually do it the night before. Then, heat up the grill to about 400 degrees. Grill each side of the meat for about 5 minutes on high heat and it's done. We like our meat a little bit red in the middle. If you want it cooked more on the well side, cook for about 6-7 minutes on each side. After you pull the meat off the grill, cut into thin strips cutting against the grain of the meat.
