Method

1. Place the beef mince, breadcrumbs, egg, parsley, onion, garlic, Worcestershire sauce and Habanero Hot Sauce in a large bowl. Season with salt and pepper. Mix with your hands until evenly combined.
2. Divide the mixture into 4 equal portions. Shape each portion with your hands into a patty about 10cm in diameter and 1.5cm thick.
3. Place the patties onto a tray lined with greaseproof paper. Cover with plastic wrap and place in the fridge for at least 30 minutes to rest.
4. Heat a drizzle of olive oil in a large, non-stick frying pan over a medium heat and cook the patties for about 4 minutes on each side or until browned and cooked through. Transfer the patties to a plate, set aside and keep warm.
5. Meanwhile, preheat grill on high. Place the hamburger buns, cut-side up, under the preheated grill and toast for 1 minute or until golden. Leave the grill on.
6. Place the patties on a tray lined with foil and top them with cheese. Place under the grill for 1 minute or until the cheese is just melted.
7. To serve, spread the bottom halves of the toasted hamburger buns with American mustard, then some mayonnaise. Top with patties, lettuce, tomato, Spanish onion, a dollop of tomato sauce and then some bread & butter pickles. Cover with the hamburger bun tops.
