Instructions

1. Place mince, onion, garlic, Worcestershire sauce and egg in a large bowl. Season with salt and freshly ground black pepper. Use your hands to shape mixture into four 8cm patties. Refrigerate for 30 mins.
2. To make the beetroot relish, combine vinegar, sugar and 1 tsp salt in a small saucepan and bring to the boil. Add the beetroot and apple, reduce heat to low and simmer, uncovered, stirring occasionally, for 6-8 mins or until beetroot is tender.
3. Meanwhile, lightly spray a large non-stick frying pan or barbecue with oil and heat over high heat. Cook onion and patties for 5 min each side or until cooked through.
4. Lightly toast bread rolls until golden. Arrange roll bases onto serving plates and top with lettuce, beef patty, onion, cucumber and relish. Place tops on rolls and serve immediately.
