What kind of food do astronauts eat?

@Physics girl phd: Nor should it, but Tang? Really?! I never could stand powdered drink mixes of any kind... yet I like slushies... clearly it's a matter of what we have as kids, and no virtue of taste.

Truly haven't tasted the stuff in years, and I'm sure I'd dislike it... but I remember my sister drinking at least two glasses a day. Surely there's not a bit of goodness nutrition-wise in it, except perhaps vitamin C.
