Instead of high-sodium packaged ramen for lunch, try healthy soba -- buckwheat noodles -- with a protein-packed vegetarian saute. Because mushrooms tend to soak up so much oil, they are "sweated" in a covered pan so that they soften in their own juices. While tofu is the traditional protein in this Japanese dish, you can substitute leftover cubed chicken or turkey for the tofu, and peas for the edamame, if you like.
