What quantity of croutons is served with a salad?

The correct answer indicates that a green scoop of croutons is the standard serving size for a salad at Denny's. This measurement is consistent with the portion control practices that aim to provide a balanced amount of toppings to complement the salad without overwhelming it. The green scoop is a recognizable measure that ensures that servers can quickly and accurately serve the appropriate amount of croutons, contributing to a consistent dining experience for guests.

The other options do not represent the standard serving size for croutons. Goldfish, for example, are a different type of snack altogether and not used in salads, while two yellow scoops or six ounces would not align with the established serving standards for croutons, which is designed to enhance the flavor and texture of the salad rather than dominate it. Knowing the proper serving size is crucial for maintaining consistency and quality in food service.
