Toast 3 slices of white bread until golden brown and crispy. Spread mayo on one side of each toasted slice.
Place one slice of toasted bread on a clean surface, mayo side up. Add one layer of romaine lettuce, 1 slice of thinly sliced, seasoned tomatoes, 1 piece of bacon broken into two small pieces, 1 slice of cheddar cheese, and a generous layer of turkey.
Place the second slice of toasted bread on top, mayo side down against the turkey. Spread mayo on the top side of this middle slice.
Repeat the layering process with lettuce, tomato, bacon, cheese, and turkey on top of the middle slice of bread.
Top with the third slice of toasted bread, mayo side down, and gently press down to secure the sandwich.
Insert long toothpicks diagonally into each quadrant of the sandwich to hold it together.
Using a sharp knife, cut the sandwich into four equal triangles for that classic club look.
Serve with your favorite side—chips, fries, or a simple salad—and enjoy!
