Well I eat a lot of bad food LOL.
But will mention I guess what I consider the worst, and that is Vienna Sausages (I prefer Libbys LOL). Who knows wtf they are made of, but they grind it down and shape it into little weenies (hee!). They are like bologna, great if you fry or nuke em, taste totally different. I cut them in half lenghways and nuke em for a minute or so (I like burnt edges) and make a sammich out of em. I also like to cut them up during the summer and use them in salads, they are great with Italian dressing.
