  • 1/4 cup olive oil
  • 1/4 cup lemon juice
  • 1/4 cup soy sauce
  • 1/4 cup brown sugar
  • 1 tbsp sriracha sauce (or other hot sauce) optional optional


  • 1 iceberg lettuce shredded
  • 8 oz cheddar cheese shredded
  • pico de gallo
  • sliced limes


  • Crush the garlic cloves with the side of a knife to break open. Set aside.
  • In a small bowl mix together the marinade ingredients and set aside.
  • With a sharp knife create cross hatch marks on both sides of flank steak (See video). Just cut the surface slightly, don't cut through meat. This is optional, but I love the crispy edges and caramelized flavors this brings.
  • In a sealable bag or container add the flank steak, garlic and marinade. Squeeze air out of bag and seal. Massage meat to get marinade into cuts and refrigerate for a minimum of 2 hours or overnight.
  • Heat grill to 350-400°Remove flank steak from marinade. Reserve marinade for basting. Grill flank steak 6 minutes per side, or until an internal temperature of 130-135°F is reached for medium rare. Baste several times during grilling.
  • Place on a cutting board and allow meat to rest 10 minutes before slicing. Be sure to cut thin slices across the grain for a tender piece of meat.
  • Char the corn tortillas on both sides, keep warm.
  • Fill warm tortilla with sliced flank steak, lettuce, cheese and pico de gallo. Squeeze some lime on top and dig in.
