Begin by washing and drying your lettuce leaves and tomatoes thoroughly. Slice the tomatoes into medium-thick rounds.

Preheat your toaster or skillet to medium heat. Toast four slices of thick-cut bread until golden brown, about 3-4 minutes per side.

In a skillet over medium heat, cook your bacon slices until crispy, about 6-8 minutes. Transfer to a paper towel to absorb excess grease.

Take one slice of toasted bread, spread mayonnaise generously, layer with lettuce, tomatoes, bacon, turkey, ham (if using), and cheese.

Place another slice of toasted bread on top and press gently. Cut the sandwich into quarters diagonally for easy handling.
