The hardest thing about this recipe is remembering to marinate the meat the day before your picnic. Once that’s done, the rest is a breeze. And the cooking time? Super quick—about as long as it’ll take your crowd to devour it!
In a dish or sealable plastic bag, combine all the ingredients. Coat the meat well with the marinade. Cover the dish or seal the bag. Refrigerate for 12 hours or overnight.
Preheat the grill, setting the burners to high. Oil the grate.
Remove the meat from the marinade. Grill the steaks for about 8 minutes or until the desired doneness, flipping halfway through cooking. Set aside on a plate and let rest for 5 minutes. Thinly slice the meat against the grain.
