* 400g (1lb) lean minced beef
* 2 egg yolks, beaten
* 1 small onion, chopped finely
* 1 clove garlic, crushed
* 4 tablespoons fresh parsley
* Salt and freshly ground black pepper to taste
* Olive oil for frying
* 1 teaspoon Worcestershire sauce
* 1 tablespoon capers, chopped
* 4 burger buns
* 100g halloumi cheese, Cheddar cheese, or a cheese of your choice
* Salad leaves and sliced tomatoes to garnish the buns

===Method===
* Fry the onions and garlic in a little olive oil until softened a little, just to take the edge off them
* Allow the onions to cool a little before handling
* In a bowl, add the onions and the rest of the ingredients apart from the buns and the cheese and squidge the mixture through your fingers so it's really well mixed
* Cut the cheese into four pieces, divide the meat into four and mould the meat around the cheese so that it's completely covered.
* Fry in olive oil for about 4 to 5 minutes per side
* Serve in the buns with the salad leaves and sliced tomatoes
