If you have never tried bison, or what is usually referred to as buffalo, you may be surprised that it is tender, juicy and flavorful. Often considered wild game, bison can be purchased at many grocery stores and specialty markets. Bison meat does not contain as much saturated fat and cholesterol as beef, making it a healthy alternative. Myra Goodman, Pamela McKinstry and Miki Duisterhof note in their book, "The Earthbound Cook: 250 Recipes for Delicious Food and a Healthy Planet," that bison meat is also higher in protein and iron than beef.
