What could I eat that won't make me gag?

Right now I’m sick. I’m usually the one who never gets sick, but finally, after it being so hot here for almost a year, with no let up, the weather turned cool, but only several hours into the deliciously cool weather, I turned up with a sore throat, achy muscles, exhaustion and a runny nose.

I stayed home from work yesterday, and am missing a birthday party today, feeling miserable and sorry for myself.

I knew I should eat something, despite my lack of appetite. Last night I tried to eat some instant macaroni and cheese, which is usually comfort food for me. It tasted metallic. Late this morning I tried to eat some leftover Chinese food, which is usually a yummy treat. It also tasted of chemicals and was way too sweet. I ditched the Chinese food and opted for a piece of buttered toast. It too, tasted off.

Any ideas (must be vegetarian) for something I could eat that won’t be totally disgusting?
