Preheat oven to 350 degrees. Butter both sides of each piece of bread. Season with garlic salt and place in the oven, bake until golden brown, checking in 5 minute intervals.
Shred lettuce and place in a bowl. Toss in parmesan cheese.
In a medium bowl, whisk together the garlic, lemon juice, Dijon mustard and Worcestershire sauce. Add the mayonnaise, Parmesan, salt and pepper and whisk until well combined.
Toss salad with dressing. Top with croutons, and serve.
If packaging for lunches leave croutons off until ready to eat. These get very soggy otherwise.
** You can use store-bought croutons and Caesar dressing if you would like.
