I like tomato soup as well - lots of vitamin C there to help clear things up.
Scrambled eggs are easy to digest, easy and quick to make, and yummy. My mom used to make scrambled eggs on toast when we were kids and recovering from a cold.
I also like oatmeal when I'm sick. Something about the warm, smoothness of it just soothes me.
And I have to admit a huge weakness of mine is Campbell's vegetable beef soup out of a can. I get the "healthy choice" version now to cut back on the sodium, but it's one of those comfort foods that makes me feel better - especially with a handful of Premium saltines.
