To create your very own Olive Garden Salad Dressing, follow these simple steps:

1. Combine Mayonnaise and Vinegar: In a mixing bowl, whisk together the mayonnaise and white wine vinegar until smooth.
2. Add Cheese and Spices: Stir in the grated Parmesan cheese, garlic powder, onion powder, Italian seasoning, sugar, salt, and black pepper.
3. Mix Thoroughly: Use a whisk to ensure all ingredients are well combined and creamy in texture.
4. Adjust Consistency: If the dressing is too thick for your liking, gradually add water until you reach your preferred consistency.
5. Taste and Adjust: Sample the dressing and make any adjustments to seasoning as needed.
6. Chill: Cover the bowl and refrigerate for at least 30 minutes to allow the flavors to develop.
7. Serve: Give the dressing a final stir, then pour over your favorite salad, or serve as a dip.
