Start by peeling the English cucumber and slicing it thinly.

In a medium-sized mixing bowl, combine the mayonnaise, lemon juice, Dijon mustard, and Worcestershire sauce. Whisk until smooth.

Add minced garlic and grated Parmesan cheese to the dressing. Mix until evenly distributed.

Sprinkle in black pepper and salt to taste, mixing again.

Blend the dressing until creamy, adding water if needed to thin.

In a large salad bowl, toss cucumber slices with the dressing until well coated.

Fold in croutons before serving to prevent sogginess.

Serve topped with additional grated Parmesan if desired.
