First fry off the onions, chopped finely, with a pinch of salt. Cook for 3mins until softened and translucent.

In a mixing bowl place the mince, onions, bread crumbs, Worcestershire sauce, mustard and garlic (crushed). Mix them thoroughly. Whisk the egg and add a little at a time to the meat mix until it is sticky enough to form patties that won't fall apart. Don't worry if you use none or all of the egg. It won't damage the flavour so use your judgment.

Next divide the mixture into 8 even balls and shape into round burgers roughly 1cm thick. Ensure they are all an even size so they will cook consistently.

To cook, turn a griddle pan up high with a little oil. Once it is piping hot place the burgers into the pan. Cook on this side at a medium heat for 5mins until you can see the bottom half of the burger begin to colour. Next flip them over and cook for another 5mins until cooked all the way through.

Serve on sesame buns with a choice of condiments.
