Put all the ingredients in a bowl and mash together with your hands. Form into burgers and then put them in the fridge to rest for at least 30 minutes.
Heat a little oil in a frying pan and fry the burgers for 3-4 minutes on each side.
Serve on your choice of burger bun with any sauces or accompaniments you like.
