Potbelly's menu features a variety of sandwiches that are all served hot on regular or multigrain wheat bread. All sandwiches can be ordered thin-cut style, in which one third of the bread is cut out. Potbelly began offering salads in February 2007. The menu also includes soup, shakes, malts, smoothies, and cookies.

Kidneys and Protein. Kidneys are bean-shaped organs in your lower back -- one is on your right side and one is on your left. Nephrons are structures inside each kidney that contain tiny tubes called glomeruli. These glomeruli are responsible for filtering your blood to remove waste products and fluid to produce urine. Kidney damage allows protein to pass through the glomeruli and move into your urine.
