Mix all of the ingredients in a zip-top bag and marinate in the refrigerator for 1-8 hours.
Heat the grill to medium-high heat. Remove the meat from the marinade. Grill for 3 minutes per side.
Remove from the grill, and let rest for 10 minutes. Slice the beef against grain.
Serve with tortillas and your favorite taco toppings.
Notes
I like marinating the meat for 2 hours. It seems to be the sweet spot for me. But you can throw it on the grill sooner or later, depending on your schedule.
