Need a good Texas Caviar recipe.?

I had this last year at a dinner it was very good and im looking for a recipe from someone who has made it themselves not someone who just searches and gives me what they found cause there's a ton of variations. Preferably a version where you mix in Italian dressing, the one i had also corn, green peppers, and black eyed peas also jalapenos, and tomatoes... Is there a big difference in using canned tomatoes and fresh tomatoes... It didn't have avacodo but im seeing some recipe's with it in there? what ya think with or without. Thanks
