Ingredients
  

  • 1 pound bison flank steak (or beef flank steak - see notes*)
  • corn tortillas for serving
  • optional garnishes: mashed avocado, finely chopped onion, finely chopped cilantro, queso fresco or cotija cheese, hot sauce

Marinade

  • 1 orange, juiced (about ½ cup)
  • 1 lime, juiced (about 2 tablespoons)
  • 2 tablespoons soy sauce
  • 2 tablespoons olive oil
  • ¼ cup cilantro, finely chopped
  • 4 garlic cloves, minced
  • 1 jalapeño, seeds removed and finely chopped
  • 1 teaspoon cumin
  • ¼ teaspoon black pepper

Garlic Lime Crema

  • ¼ cup sour cream
  • 2 tablespoons mayo
  • 1 ½ tablespoons lime juice
  • lime zest from ½ lime
  • 1 large garlic clove, minced
  • ¼ teaspoon salt

Instructions
 

  • In a shallow dish, mix together the marinade ingredients. Add the steak and make sure that both sides are well coated in the marinade. Marinate in the fridge for 4 hours or overnight.
  • Preheat the grill to medium-high heat. Remove the steak from the marinade and pat dry with paper towels. Grill over direct heat for about 2 minutes per side, or until the internal temperature reaches 135-140 degrees F. Remove from the grill, and let the steak rest for 5-10 minutes before slicing. The internal temperature will continue to rise from carryover heat bringing the steak closer to 145 degrees F for medium doneness.
  • While the steak rests, mix together the garlic lime crema ingredients.
  • Thinly slice the steak at an angle against the grain. From there, cut the strips into small pieces, if desired.
  • Warm the corn tortillas, then spread with smashed avocado and top with steak. Garnish with onion, cilantro, queso fresco and garlic lime crema. Finish with a few dashes of hot sauce, if desired.

Notes

*Beef flank steak is bigger and thicker than bison flank steak, so you will need to grill it a little longer, about 6 minutes per side until the internal temperature reaches 135-140 degrees F.
