Oh so that's what this is called..lol. I have made this for years and as I think about it, I can not remember when, where or how I came about having this recipe. The only difference is that I use lemons and jalapenos and I add fresh minced garlic, and no vinegar. It is often requested at family get togethers, especially by my son. Thanks for posting, now it has a name instead of "that hamburger dish"
