Grilled Flank Steak Tacos

"Grilled Flank Steak Tacos are an easy and delicious way to celebrate warm summer nights on the back porch! The key is to just marinate the flank steak for a short amount of time. If you marinate the steak overnight, it will become tough once grilled. So break out the grill and get dinner going for tonight! This is perfect for tacos on the back porch....enjoy! These are good enough to send your guests back for seconds."
