Serves 4

Ingredients

• D’Italiano® Original Crustini Buns
• Red onion 1 small, tough outer layers peeled and discarded
• 400 g ground beef
• 1 tsp. celery salt
• Flat-leaf parsley a handful, finely chopped
• 4 slices of prosciutto
• Oil for frying
• 4 slices of provolone (or fontina)
• Shredded lettuce to serve

Burger Sauce

• 4 tbsp. mayonnaise
• 3 tsp. sweet mustard
• 6 cornichons, chopped
• 4 pickled onions, chopped

Directions

 1. Grate the onion with a box grater.
2. To make the sauce, mix the mayo, mustard, cornichons and pickled onions and season.
3. To make the burgers, put the mince, onion, celery salt and parsley in a bowl. Season with pepper and mix well, then divide into four balls. Form each ball into a thin patty – they will shrink as they cook so make the burgers larger than your buns.
4. Pan fry the prosciutto for 2-3 minutes until crisp, then take out but leave the grill on.
5. Heat a large, heavy frying pan to hot. Oil and season the burgers then cook for 2 minutes each side until golden and cooked through.
6. Put a slice of provolone on each burger and grill for 2 minutes on high until bubbling.
7. Add some lettuce to each D’Italiano® Original Crustini Bun. Sit a burger on top, add the crispy prosciutto, spoon over the sauce and put on the bun top.
