Heat a skillet over low heat. Add bacon strips and cook slowly for about 8-10 minutes until crispy and golden brown. Transfer bacon to paper towels to drain excess grease.

Butter one side of each slice of bread and toast in a griddle or skillet over medium heat until golden brown, about 3-4 minutes on each side.

Spread a generous layer of mayo on the unbuttered side of each toasted slice. Consider adding aioli for a gourmet twist.

On one slice of bread (mayo side up), layer the crisp lettuce, tomato slices seasoned with salt and pepper, turkey, and finish with bacon strips.

Place the second slice of toasted bread on top, buttered side facing out. Press down gently to compact the sandwich.

Toast the assembled sandwich in the skillet or griddle over medium heat for another 3-4 minutes on each side until heated through and crispy.

Carefully remove from skillet, slice diagonally, and enjoy!
