  4. Heat a griddle pan over a high heat until smoking. Remove the steaks from the marinade, pat dry and drizzle with oil then sear for 1-2 minutes each side until charred but still rare inside. Set aside to rest for 5 minutes. 
  5. Toss the tomatoes with the red onion and the rest of the coriander leaves. 
  6. Slice the steak and serve in the warm tortillas with the tomato and red onion relish and the taco shop guacamole.
