Here's one healthy diet resolution that is both easy and delicious to make! Whole soy contains phytochemicals which have been shown to help prevent heart disease and several forms of cancer. Soybeans are packed with fiber and protein, and tofu - which is made of whole soybeans, not soy isolates - is a terrific source of protein as well as heart-healthy unsaturated oil. Experiment with tofu and tempeh (a fermented soy food), replace ground beef with beans or a whole-soy substitute, and toss chickpeas rather than chicken into salads. You'll still get the protein, but with far less fat and more fiber.
Not sure where to start? I suggest a Southwestern favorite - Mole Pinto Beans.
