Turning vegetables into (tasty) food

What are your favorite simple recipes for turning raw vegetables into something tasty?

I'm looking for dishes which require at most:
* ~1-3 different vegetables
* ~0-2 other ingredients (spicing doesn't count vs. this limit)
* Minimal prep time, and minimal to medium cooking time

(I'm looking for things at least a touch more interesting than "steam, salt to taste", though that does meet the criteria as stated.)

EDIT/ADDENDUM: I'm allergic to soy. A small splash of soy sauce I can handle, but soy sauce marinades or tofu as a main ingredient aren't options.
