Combine the marinade ingredients in a bowl and set half of this aside for later. Pop the steaks in the remaining marinade ensuring they are well coated and leave for around 6-8 hours.
When ready to cook, grab the marinated steaks out of the fridge to come up to room temperature as you light up Roccbox and pop the sliced vegetables in the reserved marinade to take on some of that beautiful flavour.
To make the salsa, combine the ingredients in a bowl with a little seasoning and the roughly chopped coriander (reserve the picked leaves for garnish) and pop onto your table for later.
Heat a cast iron pan in Roccbox with a drizzle of olive oil, shake the excess marinade off the steaks, season with a little salt and cook for around 3 minutes on one side, flip over for a further 2-3 minutes, check the steaks are cooked to your liking and leave to rest.
Using the same pan, throw in the marinated vegetables and cook, shaking regularly until charred and softened.
Finally, heat the tortillas lightly and slice the steaks thinly against the grain before wrapping it all up and getting stuck in!
