Place about 4 cups of water in a medium size saucepan and bring to the boil. Add the potatoes and sweet potato, cover and boil until very tender. About 10 minutes.

While the potatoes are cooking, heat 1 tbsp olive oil in a non stick frying pan then add the onion and garlic and fry until fragrant and golden. Add the carrot and broccoli and fry for 5 minutes. Then add the curry powder and fry, stirring for 1 minute.

Mash the potatoes with a drizzle of olive oil and salt & pepper until they are smooth.

Stir the onions, carrots and broccoli into the mashed potato.

Allow to cool slightly and when you can handle the mixture, form little burgers with your hands, dip the burgers quickly into the egg. Fry in 1/2 tbsp olive oil in the same frying pan you used for the onions on a medium hight heat. About 1 minute on each side.

Serve with the spiralled carrot, red cabbage, baby marrows and lettuce leaves in bowls.
