We do it fairly often... in fact here's a great recipe:
1 1/2 lbs lean flank steak
3/4 cup rose wine (as always, one for chef)
1 teaspoon fresh ground black pepper
1/2 teaspoon salt
1/4 teaspoon dried rosemary, crushed
1 medium onion, sliced
1 garlic clove, crushed
vegetable oil cooking spray
How to:
Trim fat from steak.
Combine steak and next 6 ingredients in a large zip lock bag, and seal, marinating in fridge 8 hours, turning occasionally.
Remove steak from marinade, reserving marinade.
Place steak on a rack coated with vegetable cooking spray and place rack in broiler pan.
Broil steak 3 inches from heat 7 minutes on each side or to desired degree of dines.
Cut steak diagonally across grain (always) into thin slices.
Keep warm.
Pour reserved marinade in a large skillet.
Bring to a boil, and cook 5 minutes or until liquid evaporates to a thickness you'd like, stirring occasionally.
Serve onions with steak.
Try it on the grill in summer... and serve with a nice rose'. I know it's pretty passe', but we still like a Portuguese product called "Lancer's"... comes in a faux terra-cotta bottle...
