  1. Step 1

    Combine the vinegar, sugar, 2 tbs water and a pinch of salt to a small saucepan over high heat. Bring to the boil. Place the red onion in a heatproof bowl. Carefully pour the vinegar mixture over the onion. Set aside for 10-15 mins to soak. Drain well.
  2. Step 2

    Meanwhile, heat half the oil in a clean saucepan over medium heat. Add the white or brown onion and season with a pinch of salt. Cook, stirring regularly, for 15 mins or until the onion caramelises.
  3. Step 3

    Heat a frying pan or chargrill over high heat or until just smoking. Season the steak with a pinch of salt and drizzle with the remaining olive oil. Cook the steak, in batches, for 30-45 secs each side or until cooked to your liking. Transfer to a plate to rest.

    Spread the bread base with mayonnaise and top with the lettuce, tomato, steak and red onion. Spread the bread top with mustard and top with the cheese and caramelised onion. Carefully top the bread base with the bread top. Cut the sandwich into 4 even pieces to serve.
