Earlier this year, the chef made a classic cheeseburger using tuna instead of beef patties Described as one of the 'favourites' on the Fish Butchery menu, the pricey $20 takeaway burger includes charcoal grilled Mooloolaba Yellowfin tuna fillets, cheddar cheese, 'lacto-fermented' cucumber, lettuce and optional 'swordfish bacon' for $8. A similar dish is on the menu at Saint Peter for $38. It's not the first time the masterful young chef has wowed with his creations, with Niland coming up with an epic gourmet sandwich - complete with ocean trout 'salami', kingfish 'mortadella' and swordfish 'belly bacon'. Niland, who's known for cooking with every part of a fish, unveiled the 'Muffuletta', which looks remarkably similar to a deli-style sandwich, except the 'sliced meats' are made entirely from different types of fish.
