Mini Cheeseburgers

INGREDIENTS:

• 500g beef mince (makes 10)
• 1 tablespoon Dijon mustard
• 1 1/2 tablespoons olive oil
• 1 onion, thinly sliced
• 10 small slices cheddar cheese
• 10 small burger buns, halved
• 2 cups shredded iceberg lettuce
• 10 slices of tomato
• Tomato or barbeque sauce, to serve

METHOD:

• Combine the beef with the mustard and some salt and pepper and mix to combine. Form into 10 patties and refrigerate for 30 minutes.
• Place 1 tablespoon of olive oil into a frying pan over a moderate heat and add the sliced onion. Cook for 15-20 minutes or until nicely coloured and crispy, stirring every now and then.
• Preheat a chargrill to moderately high. Brush the patties with the remaining oil and cook for 2.5 minutes. Turn over, place a cheese slice on top of each patty and cook for a further 2 minutes or until cooked through. Set aside.
• Top the bottoms of the buns with patty, tomato and lettuce. Add the onions and a squirt of sauce.
