Slippy Burgers

I got these crazy, wonderful burgers from My Great Recipes card club collection many years ago. Don't even know if the club is still in existence or not. They were named "Smoky Surprise Burgers" originally. Because they're slippy and slide all over when you cook them my son dubbed them "Slippy Burgers" and that's what we've called them since. Thought it'd be nice to share the recipe now as July 4th. is coming and they're great for an outdoor get together. Add your favorite Tater Salad, Chips, pickles, etc. Anything goes well with these burgers and they're good served any time of the year. ENJOY!
