Heat up the oil in a frying pan and add the diced onions

Reduce down the heat and let the onions sweat slowly adding in the garlic to ensure it doesn't burn and become bitter

Add the beef to a mixing bowl and break up with your fingers

Tip in the onions and garlic,once cooled slightly and mix together thoroughly

Add salt and pepper and the Dijon mast

Pour in the egg and ensure that it has been mixed right the way through the beef and onions

Separate the mixture into 4 portions and start moulding using your hands into burgers.create a depression in the centre this will ensure the burgers cook evenly and flat place in the fridge to chilled and stiffen

Once chilled and with the barbeque lit and the coals simmered down place the burgers in the BBQ

Ensure that each side has sealed,if not they'll fall apart when you lift them off.Turn them over until cooked through or to the desired pinkness in the centre
