I found and wrote down this recipe awhile back. I only remember that the flank steak was to be grilled. This is the marinade recipe for it. I guess you're supposed to marinate it overnight and turn it over once during the process.
It looks pretty spicy.
2½ lb flank steak
2 red onions, chopped
2 cloves of garlic, minced
2 tbsp fresh ginger, grated
¼ cup olive oil
1 cup parsley, chopped
1 tsp cumin
1 tsp tumeric
1 tsp black pepper
1 tsp red-pepper flakes
Alright, maybe Erik could help me out. How hot do you think the grill should be? I think medium low sounds about right. Take the marinated steaks out and put them on the grill. Cook to your preference. I always like my beef medium rare, so, maybe 3 minutes on each side? I dunno. Somebody experiment with this and tell me what you come up with.
