The Big N’ Tasty is one of the sandwiches sold by the international fast food chain McDonald's. It is designed to compete with the Burger King Whopper sandwich. A similar variation called the Big Tasty, without the center N, is sold in parts of Europe, South America and the Middle East.
The Big N' Tasty is a hamburger, consisting of a quarter-pound, or 4 ounces (110 g), beef patty, sesame seed bun, lettuce, tomato slice, mayonnaise, ketchup, chopped onions, two pickle slices, and grill seasoning. Cheese can be added on request. The Big Tasty configuration is somewhat different, consisting of a third-pound beef patty, 5-inch sesame seed bun, square-cut lettuce, two tomato slices, Big Tasty sauce (which has a smoke flavor), sliced onions and three slices of Emmental cheese.
