Steak Sandwich

Not many things beat a good steak sandwich, and this is definitely a good one. We griddles some lovely flat iron steaks from our friends at Market Porter and popped them between slices of toasted ciabatta with caramelised red onion, watercress and our Gran Luchito Chipotle Mayo.

How to make it

  1. Begin by melting the butter in a pan (you’ll need a lid for it later) along with 2 tbsp olive oil and the sugar. Heat until sugar has melted.
  2. Add sliced onion and cook on a medium/high heat for about 5 minutes.
  3. Add the vinegar and place a lid on it, reduce the heat to low and cook for a further 20 mins, turning the onions after 10.
  4. Remove lid and cook for another 10 mins uncovered or until they go all sticky.
  5. Meanwhile, heat a pan and get it as hot as possible.
  6. Toast ciabatta slices.
  7. Cover steaks in a little olive oil, salt & pepper. Add steaks to pan and cook for about 3 minutes on each side (this will give you rare/medium steaks).
  8. Remove from pan and leave to rest for about 5 mins.
  9. Wipe ciabatta slices through cooking juices from steak.
  10. Spread Gran Luchito Chipolte Mayo onto the ciabatta slices and top with watercress, followed by onions.
  11. Slice steaks with a sharp knife and lay on top of onions. Top with ciabatta and enjoy!
