Steak Sandwich

Savor the bold flavors of a juicy steak sandwich, featuring tender sirloin, caramelized onions, and melted provolone, all nestled between crusty bread. Ideal for a hearty weeknight dinner or a weekend treat.

• 250 g sirloin steak
• 1 large onion
• 2 teaspoons American mustard
• 4 slices nice bread
• 50 g provolone or fontina cheese

Method

1. 1

   Peel and slice the onion into 1cm-thick rounds. Add to a frying pan while you peel the onion.

2. 2

   Meanwhile, cut the steak between two sheets of greaseproof paper and pound with your fist until just under 1cm thick. Sprinkle with a pinch of sea salt and black pepper then brush all over with the mustard.

3. 3

   Add a good splash of red wine vinegar to the onion, toss for 1 minute over the heat, then divide between two slices of bread, leaving the pan on the heat.

4. 4

   Sear the steaks in the screaming hot pan for just 40 seconds on each side, then slice and lay over the cheese, cover, turn the heat off and leave to melt for 40 seconds more.

5. 5

   Lay the steak on top of the onion, pop the other slices of bread on top, drizzle with a little extra virgin olive oil, and devour.
