01 - Toast all 12 slices of bread until golden brown. Butter each slice lightly if desired for extra richness.
02 - Spread mayonnaise evenly over one side of each toasted bread slice.
03 - Place 4 bread slices mayonnaise-side up on a flat surface. Top each with lettuce leaves, a few tomato slices, and season with salt and pepper.
04 - Add a second bread slice mayonnaise-side up on top of the first layer. Layer with sliced chicken or turkey, followed by cooked bacon strips.
05 - Top the meat layer with another round of lettuce leaves. Place the final slice of bread mayonnaise-side down to finish each sandwich.
06 - Secure each sandwich with cocktail sticks at all 4 corners. Using a sharp knife, cut each sandwich diagonally into quarters to form triangles.
07 - Serve immediately alongside potato chips or dill pickles if desired.
