Well, if we're doing crappy food and unhappy circumstances I have a few.

One was when my brother and I were in our late teens and lived alone, and spent all our money on alcohol and drugs. We'd buy 2-3 whoppers on dollar Whopper day, which was fine. In between though occasionally I wanted some food, so I'd deep fry batter made out of flour (nothing else) in a saucepan and eat it with ketchup.

When I was in 4th grade, one time I had been arguing with my mother and stomped off. Hours later she said dinner was ready. I came and one of the dishes was something like mashed potatoes. I asked, is this mashed potatoes? She said NO, it's mashed TURNIPS. I figured she was being sarcastic. I grabbed some mashed potatoes and when I tried them I was AAAAAGH wtf is this! Oh. It was mashed turnips.

Then there's all the bizarre things I've eaten in light of having Celiac disease and Type 1 Diabetes, such as a hot dog with raw cabbage and Tabasco sauce for breakfast. I also lived in my car mainly at campsites for 2-3 years, so I'd eat stuff like roasted chicken from a mason jar, straight out of the cooler with a pickle and a jalapeno.
