Beef ‘n’ bean burger

Instructions

1. In a large bowl, combine beans, mince, spring onions, breadcrumbs and egg. Using your hands, shape mixture into four 1.5cm-thick patties. Refrigerate, covered, for 15 minutes to firm.
2. Spray a non-stick frying pan with oil. Over a medium-high heat, cook patties for 4-5 minutes each side, or until just cooked through. Remove and keep warm. Spray pan with more oil and cook red onion for 2 minutes each side.
3. Place a lettuce leaf and a slice beetroot on the base of each bun. Serve topped with a patty, beetroot slice, onion rings and a spoonful of salsa.
