I'm so impressed with the Yahoo tips lately, here's a good'un:

Firm Up Your Dinner Plans

Deciding ahead of time what you are having for dinner will keep you from grabbing the wrong foods when you are in a pinch. Set a deadline for yourself, say 3 p.m., to know what you're serving. This will give you plenty of time to plan and pick up what you need. If time is tight, plan on a quick recipe or pick up nutritious convenience items such as canned minestrone soup, precut greens for a salad and pre-cooked chicken to toss on top. Taking 5 minutes to plan can mean a lifetime of balanced meals and good health for you and your family!
