The following marinade recipe is a grilling staple for my Mom, and now me. Neither of us really remembers where it first came from, but we love it. My Mom started using it for fajitas back in the 70s when fajitas were just becoming popular to make at home. We’ve used this marinade with chicken and beef, like flank steak. It’s really versatile and has lots of flavor. We hope you enjoy it as much as we do.
