After you have peeled your beetroot, grate the beetroot coarsely into a bowl.
Over the sink, squeeze handfuls of the beetroot to get some of the liquid out. It will look like a crime scene!
Next, mix the beetroot, garlic, flour and the egg, along with a good pinch of salt and pepper.
When well combined, stir in the feta.
Form the mixture into four burgers with your hands.
Heat a large frying pan over a medium-high heat with 3 tbsp olive oil and fry the burgers for 10 minutes on each side until crisp on the outside and cooked through.
Depending on how thick your burgers are, you might find the middle of them is quite squidgy and raw, which is fine if you are OK with raw egg. Otherwise make sure the burgers are thin and cooked through.
