i simply used lime for the marinade. i grilled my steak then finished it off in the pan i caramelized my onions in for the color && extra flavor. then mixed some mayo..sour cream && fresh garlic for the spread.. .the rest is up to you. i had some lettuce..you can add tomatoes..cucumbers..yumm && spinach (done that before) very easy yet delicious!!
grill steak 5 - 7 mins. on each side then 2 - 3 mins. on each side on stove top.
