Olive Garden Italian dressing

Ever wonder how to make the same dressing that restaurants do in the comfort of your own home? Well I found the Olive Garden recipe here and I plan on making this for my roommates once I hit Stop & Shop. Or maybe I'll surprise my parents and make it for dinner once I'm back in NJ.

Ingredients:
1/2 cup mayonnaise
1/3 cup white vinegar
1 teaspoon vegetable oil
2 tablespoons corn syrup
2 tablespoons parmesan cheese
2 tablespoons romano cheese
1/4 teaspoon garlic salt
1/2 teaspoon italian seasoning
1/2 teaspoon parsley flakes
1 tablespoon lemon juice

Directions:
Mix all ingredients in a blender until well mixed. If this is a little to tart for your own personal tastes please add a little extra sugar.
