In a large bowl, mix together your ground lamb with the finely chopped herbs, nuts and apricots.
Using slightly damp hands, divide the mixture into four. Make each amount into a burger shape. Each burger shape should have around a 9cm diameter. Cover and chill in the fridge for 20 minutes.
Grill burgers on a prepared barbecue or preheated moderate grill for 5-7 minutes on each side until cooked and any meat juices run clear.
Serve your lamb burger in brioche hamburger buns with a salad garnish and a selection of relishes.
