A BLT sandwich is a popular type of sandwich that consists of three main ingredients: bacon, lettuce, and tomato. These ingredients are typically layered between two slices of bread, often toasted for added texture. The sandwich is known for its simple yet delicious combination of flavors. To prepare a BLT, crispy cooked bacon is placed on the bread, followed by fresh lettuce and slices of ripe tomato. Many people enjoy adding mayonnaise for extra creaminess, but this is optional. The BLT is a classic choice for lunch or a light meal, appreciated for its satisfying taste and ease of preparation.
