Help me, Obi-Flist. You're my only hope!

Although I have resolved to EAT MORE in 2008 than in 2007, I do intend to eat healthier. I have a full-time job, plus a husband and kids, AND I occasionally whip out ye olde laptop and write something. Dudes, I need more energy.

Healthy eating, however, is a) Expensive, and b) Time-consuming.

So, HELP!

Do you have a favorite healthy recipe that is either quick and easy, or inexpensive, or can be made in such quantities that it lasts a few days?

I'm especially interested in stuff that is satisfying during the winter. (I'm the Summer Smoothie Queen, after all. *confers favor*)
