I actually like shopping, so I don't know that my response will be as helpful - but I love to freeze things. (I bought a chest freezer when we moved here so I'd have more freezer space.) Keeping enough veggies around is easier when a lot of them are frozen (I usually get those pre-frozen), but you can also make ahead entrees and freeze those. Pop them out, bake them, eat - so you can go with the craving of the moment but not have to get ingredients together and do all the prep work right then.

Of course, I say that on a day when my husband and I tried a couple tastes of an experimental veggie bake and dumped it in the trash. *shudders* The tried and true recipes have been pretty decent, though. It's when I experiment beyond my cooking skills that life gets interesting.
