Preheat the oven to 180°C.

Add butternut, sweet potato and oil in a roasting tray. Sprinkle cinnamon, nutmeg, salt and pepper.

Roast in the oven for 30 minutes, until soft. Leave butternut and sweet potato to cool.

Mix lentils, veg and half the almonds in a bowl. Mash the mixture together until even. Taste and add more seasoning if necessary.

Split the mixture into 6 evenly sized balls. Shape into burger patties and coat in the remaining almonds.

Drizzle oil into a non-stick frying pan on medium heat. Fry the patties for 1 minute on each side until golden brown.

Put your burger patty on the middle of a whole ice berg leaf. Wrap your burger up in a lettuce leaf and serve.

Add favourite burger toppings like guacamole, salsa and fresh sprouts.
