A crunchy sandwich is a type of sandwich that has a crunchy texture, usually due to the addition of crunchy ingredients such as nuts, seeds, or croutons. Two examples of crunchy sandwiches are the taco and the BLT. The taco is a Mexican-style sandwich that typically consists of a crunchy tortilla filled with meat, cheese, lettuce, tomatoes, and other toppings. The BLT is an American classic sandwich made with bacon, lettuce, tomato, and mayonnaise on toasted bread.
