Ingredients

  • 1 green bell pepper chopped
  • 1 yellow bell pepper chopped
  • 1 orange bell pepper chopped
  • 8 oz sirloin steak fat trimmed
  • ½ red onion thinly sliced
  • 6 organic flour tortillas
  • 1 teaspoon unsalted butter
  • 1 avocado sliced into thin pieces
  • 1 teaspoon cilantro optional
  • 1 lime juice of, optional

Steak Marinade

Instructions

  • Wash and trim the fat from the steak. Pat dry.
  • Pour ½ tablespoon of soy sauce on each side of the steak (1 tablespoon total).
  • Combine the seasonings in a bowl.
  • Sprinkle the seasonings on both sides of the steak. Place the steak in a Ziploc bag.
  • Add ½ tablespoon of soy sauce to the Ziploc bag. Seal the bag, removing all air.
  • Pat the outside of the bag to ensure added soy sauce saturates the meat.
  • Place in fridge to marinate at least 4-6 hours, preferably overnight.
  • Add the chopped veggies to a grilling tray. Grill for 4-5 minutes. Flip and turn the veggies to the other side. Grill an additional 2-3 minutes until soft.
  • Add the tortillas to the grill. Grill each side for about 1 minute.
  • Grill steak to preferred doneness (i.e. medium).
  • Melt 1 tablespoon of unsalted butter in the microwave for 30 seconds and stir. After the steak has reached the desired doneness, using a cooking brush, brush the butter onto both sides of the steak while it’s on the grill.
  • Remove the steak from the grill and allow it to cool for 5 minutes.
  • Place the steak horizontally on a cutting board, and slice steak into pieces.
  • Place the tortilla on a flat surface. Fill with the veggies, avocado, and steak. Serve!
