Heat the sugar & vinegar on the stove on med-low heat until sugar is dissolved and then add oil and heat through. Stir well. Combine with other ingredients and stir. Chill in fridge thoroughly about an hour. You may want to drain some of the juice just before serving. I make extra because I love it! Serve with Scoops white corn chips or Fritos Scoops You can also make this same liquid sauce for any pasta salad recipe!! It's kind of a basic vinegar sauce. Sometimes I add pasta to this too and make it as a salad instead of a dip.
