mom's flank steak

I have a photocopy of this recipe, handwritten on KFIA letterhead (we lived in California) and noted "SL July 86 P 385". I think the SL is Southern Living...but does Southern Living have 385 pages? Someone more informed will have to weigh in here.

Anyway, this is really the only way I know to make steak, and it's what Katie always wanted for her birthday dinners growing up, and it's quick and very delicious. I will reproduce it here as written.

Tangy Flank Steak

1-1 1/2 # flank steak
1/2 c veg oil
3 T vinegar
3 T lemon juice
2 T worcestershire sauce
2 T soy sauce
1 1/2 T fresh chopped parsley
1 1/2 t salt
2 t dry mustard
1 t pepper

Combine ingredients
Marinate 2 hrs covered in refrig

We always broil it instead, 5-7 minutes per side. Tonight we had it with mashed red potatoes on the side.
