For me, I always eat noodles of some sort, with not much on them. Spaghetti with just parmesan cheese, ramen noodles (without the packet) with seasoned rice wine vinegar and a little sesame oil, maybe even angel hair pasta with butter and brown sugar. Always with a big glass of milk. Those who know me know that I am a plate cleaner. If I like what I have on my plate, there's hardly a speck of it left when I'm done. I scrape my ice cream bowl clean. I use bread to sop up every last bit of a good sauce or soup. I eat edible garnishes. So it probably won't surprise you to hear that when I'm by myself, I sometimes LICK THE BOWL.
When my dad has to fend for himself, he always eats Zesta crackers and milk.
Tyson eats crackers, cheese, and good salami.
What about you? I'm really curious to know what you eat when there's no one else around!
