Final answer:
The dressing you receive when substituting fries for mixed greens varies by restaurant and dish; it could include vinaigrette, ranch, or Caesar, among others. Always ask your server for available options and mention any dietary preferences.
Step-by-step explanation:
The dressing that comes when fries are substituted for mixed greens often varies depending on the restaurant or specific dish you are ordering.
Generally, when you order a meal that includes mixed greens instead of fries, the salad may be dressed with options such as a vinaigrette, ranch, Caesar, or other house dressings.
It's best to ask the server for the available dressing options or if you can choose from their selection. If you have specific dietary preferences or restrictions, this would also be the best time to inform them to ensure you get a dressing that suits your needs.
