  • 1 1/2- 2 lbs flank steak
  • 1 serrano chile diced
  • 2 large garlic cloves minced
  • 2 tbsp Worcestershire sauce
  • 1/2 cup Tamari or soy sauce
  • juice and zest of one Persian lime (about 1/2 cup)
  • 1 small white onion sliced
  • 1/4 cup extra virgin olive oil
  • 1 handful cilantro chopped
  • 1 tsp cumin
  1. Whisk together all the ingredients. Immerse and cover the steak with the marinade in a large resealable zip lock bag or lay it flat in a baking dish. Marinate the meat 4-6 hours in the refrigerator, turning occasionally or overnight until you are ready to grill.

Recipe Notes

Slice the cooked flank steak across the grain. This means cutting across the fibers rather than along with the grain of the meat.

If you are gluten-free use Tamari instead of soy sauce.
