Cut the crust from the bread. Cut each slice of bread into four rectangles. Place bread rectangles on a baking sheet and toast until golden brown. Allow toast to cool before proceeding.
Cut bacon slices into thirds. Cut cherry tomatoes in half.
Assemble appetizers: Spread one side of each toast with mayonnaise. Top with one piece of bacon, a lettuce leaf and half a cherry tomato. Sprinkle with salt (I used a Hawaiian black sea salt in the photo).
