Vegetarian burgers with sweet chilli sauce

Instructions

1 Spray a large non-stick frying pan with oil and set over a medium heat. Add the kumara and courgette and cook for 3–4 min until soft and quite dry. Add the garlic, soy sauce and parsley and cook for 30 sec. Set aside.

2 Whiz the sausages and egg to a paste in a food processor, then mix through the breadcrumbs and kumara mixture. Shape into 4 burger patties.

3 Spray a non-stick frying pan with oil and set over a medium-high heat. Add the burgers to the hot pan and cook for 4–5 min on each side (turn only when cooked on one side so the burgers don’t break up in the pan) until cooked through. Meanwhile, toast the rolls.

4 To serve, fill each roll with a burger, sliced onion, tomato and avocado, and watercress and sweet chilli sauce.
