Step 1

Heat the oven to 200°C/fan180°C/gas Peel the beetroot, grate and wrap in a folded clean J-cloth. Squeeze out as much liquid as you can.

Step 2

Put the beetroot in a bowl with the lentils. Finely chop and add the garlic, chilli, ginger and mint. Crack in the egg. Mix in the curry powder, salt and pepper and 1-2 tbsp flour (just enough to hold it all together).

Step 3

Heat a glug of oil in a pan. Divide the beetroot mix into 4 and shape into burgers. Dust well with flour on both sides. Once the oil is very hot, fry the burgers for 2-3 minutes on each side until golden.

Step 4

Put the burgers in a baking tray and bake for 5-6 minutes until piping hot. Serve topped with feta on buttered, toasted buns, with salad leaves and a few lemon wedges.
