Put all ingredients in a mixing bowl, then combine with your hands, kneading the mixture well.
Divide the mixture into 4 balls (or 6 small ones for mini burgers), then slightly flatten them between your palms. Put them on a plate and rest in the fridge until you’re ready to cook.
Heat your BBQ/grill/griddle pan or oven and cook them for 5 minutes or so on each side until charred and golden. If you prefer lamb burgers medium rare, cook them for approx. 3-4 minutes on each side.
Assemble the burgers with your chosen toppings and condiments, then serve.
