Ingredients

  • 1 pound skirt steak or other quick cooking steak
  • 2 Tablespoons olive oil
  • 1 red onion, thinly sliced
  • 1 red bell pepper, thinly sliced
  • 1 yellow bell pepper, thinly sliced
  • 1 orange bell pepper, thinly sliced
  • 6 flour tortillas
  • 1 red chilli pepper, thinly sliced
  • 1 avocado, sliced
  • 1 bunch cilantro chopped

For the marinade:

  • ¼ cup olive oil
  • 1 Tablespoon cumin
  • 1 Tablespoon brown sugar
  • 1 Tablespoon Chilli Powder
  • ¼ teaspoon oregano

Instructions

  • In a mixing jug, combine all the marinade ingredients and whisk until incorporated. Place the steak in a shallow dish, so that it fits snuggly. Pour the marinade over the beef and set aside to marinate for at least 30 minutes.
  • While the steak is marinating, slice and cook the vegetables. Place the oil in a non stick skillet and heat on high. Add the peppers and onion and cook until the vegetables are tender, but still have a slight crunch. Place in the oven to keep warm while you sear the beef.
  • Heat a grill pan over very high heat. Toast the flour tortillas in the grill pan for about a minute each side. Once the tortillas are toasted, place the steak in the pan and grill on each side for about 5 minutes, or until each side is charred and smokey. Set aside to rest for 10 minutes before slicing.
  • Place the veggies and the sliced beef in a bowl to serve at the table along side the tortillas, sliced chillies, avocado, and cilantro.

Notes

Note 1. The marinade can be made a day (or several days) in advance and left in a container in the fridge ready for the beef.
Note 2. The beef can be marinated the night before grilling to add extra flavour. Simply place the steak and marinade in a ziplock bag in the fridge, or place in a shallow dish and cover with plastic wrap.
