Hamburgers

2 tbsp olive oil
1 onion, diced
600g prime minced beef
dash worcestershire sauce
1 tbsp tomato relish
sea salt and freshly ground black pepper
1 egg, lightly beaten
2 slices bread, crumbled
4 soft burger buns
fillings: lettuce, tomato, grated carrot plus all the good stuff like chutney, cheddar cheese, crispy bacon …

Heat 1 tbsp oil in pan over medium heat and cook onion for 5 minutes until softened and lightly coloured. Set aside to cool completely.
In a medium bowl, mix mince with worcestershire sauce and tomato relish and season with salt and pepper. Add cooked onion, egg, breadcrumbs, and mix well.
Take a small spoonful of mixture and cook this to test the seasoning. Adjust if necessary.
Shape remaining mixture into 4 large patties with your hands. The patty should be slightly larger than the bun, as it will shrink when it cooks.
Place the shaped patties on a flat plate, cover and refrigerate for 30-60 minutes to help them become firm.
Place a large heavy based pan over high heat, add 1 tbsp oil and gently place burger patties in pan. Reduce heat to medium and cook burgers for 5 minutes on one side, then carefully flip over to cook the other side. Place a slice of cheese on top of each, to melt as the burger cooks. Cook on second side for a further 4-5 minutes.
Split bread buns in half and warm the buns in the oven slightly, then assemble.
