There is a package mix I like to keep on hand at all times; Good Seasonings Italian Dressing. Sometimes zesty style, sometimes regular. Doesn't matter. They are similar. I use it not only to whip up yummy Italian dressing for salads, but this is what I drizzle on our Italian Ciabatta bread sandwiches, I use it with cream cheese for delicious dips with Wheat Thin crackers and I use it mixed in with mayonnaise and sour cream for our favorite Bread Bowl Sandwich.
This Italian Dressing starts with a package mix and dresses it up a bit. Try it! Some people think it tastes just like Olive Garden's house dressing.

1/4 c rice wine vinegar (or use white vinegar if it's all you have on hand)

1 t sugar
1/2 teaspoon garlic powder
1 T mayonnaise
3 T water
