I've made Texas Caviar for many years. If you are from the South, you probably have your own favorite recipe too! There really is nothing complicated about this dish at all, but I would recommend making the recipe a day ahead so you can store in the refrigerator overnight so the flavors can meld. I have made my own dressing for this before which is just a great Italian Dressing, but your favorite bottled dressing works just fine. I used the Olive Garden Italian Dressing that I found at HEB but any good Italian Dressing will work! I got my Olive Garden dressing at HEB but I know Walmart has it too: https://www.walmart.com/ip/Olive-Garden-Signature-Italian-Dressing-16-fl-oz-Bottle/.
