This is great as a main dish, but if you have left-overs or make a double batch, the chicken can be cut into strips and frozen, then used on salads or in wraps for lunch. I have two recipes I'm posting that use these chicken strips: Chili-Lime Chicken and Avocado Wraps, Chili-Lime Chicken Mexi-Ranch Salad. I also use the leftovers for impromptu fajitas. (In our house, these are "Make it your own self" meals.)
I've never tried this marinade on flank steak, but I bet all of the above would be great with it as well. If you try it before I do, please let me know how it turns out!
