In a large bowl, combine the lamb, beetroot, egg, mint and garlic.
Season to taste with salt and freshly ground black pepper and mix thoroughly.
Divide into 4 equal portions.
Take one portion and flatten it in the palm of your hand.
Place a cube of feta in the middle and draw the meat up and over the cheese, moulding it into a burger shape and taking care to ensure the cheese is totally surrounded.
Repeat with the other meat portions and rest in the fridge for 30mins.
Heat a griddle pan or BBQ to medium hot and cook the burgers for around 6-8mins on each side.
Check they’re cooked by inserting a skewer into the middle.
If it comes out piping hot to touch they are cooked, if not cook for a further minute or so.
Serve the burgers in buns with salad.
These are great with sweefire-infused beetroot, available from Tesco and Waitrose.
