Here is my copy of the dressing Theresa was looking for. ~ Mary B. Michigan
Olive Garden Italian Dressing
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
Mix all ingredients in a blender until well mixed. If this is a little too tart for your own personal taste, please add a little extra sugar.
