What is "melba toast"?

Melba toast is a type of dry, crisp and thinly sliced toast that is made from thinly sliced, toasted bread. To make Melba toast, a loaf of bread is sliced thinly and then toasted until it is crispy and golden brown.

Melba toast can be made from a variety of breads, but is typically made from white bread or whole wheat bread. It is often served as a snack or as a garnish for soups and salads. Melba toast was invented in the late 19th century by a French chef named Auguste Escoffier, who named it after the Australian opera singer, Dame Nellie Melba. Melba toast is a versatile and delicious food item that is enjoyed by many, and is often used as a low-calorie alternative to regular toast or crackers.
