Yum. Okay, I normally don't make cookbook recommendations, but I can't help it with this one.
I've been using Jacques Pepin's
Fast Food My Way in my kitchen for a while, and I've come out with fabulous meal after fabulous meal. Tonight's dish is salmon in mirin, a beautiful dish I wouldn't have thought of making on my own, and it took about six minutes of prep time (mostly engrossed in poking through the pantry, wondering aloud, 'where in the world did I put my bottle of mirin!?') Pepin does a really good job of distilling gourmet meals for cooks who are somewhat strapped for time.
(A note, though -- some of the recipes you'll want to shop for ahead of time, as this is not a 'use what you have on hand' cookbook.)
If you're looking for fast, full-flavored meals, I highly recommend it.
Faithful
