Hmmm, I've made some pretty craptastic things, but I've blocked many of them out of my memory. Here's what I remember from my childhood/early adulthood:
"Jungle Juice" - Mad Dog 20/20, fruit juice(s), chopped fruit, maybe vodka or Everclear if we really wanted to be sick--er, have a good time.
"North Dakota pasta" - elbow macaroni and ketchup
"lasagna" made with spaghetti sauce from a packet (mix w/water & tomato paste), plain ground beef, curly lasagna noodles and cottage cheese. (Hey, my family was German, gimme a break)
Dozens of "hotdishes" made with canned cream of mushroom/celery/chicken/crap, elbow macaroni and plain ground beef (heavens forfend we would use any of the decades-old spices in tin cans in the cabinet)
Lots of "salads" that involved various colors of Jello with fruits/cottage cheese/other stuff suspended in it.
CI's Chicken and Rice casserole from Cover and Bake
I've had much, much better food in Lutheran church basements. Really.
