Mmmm...sardines

Though some of you (or your lunchmates) may find them unpalatable, sardines make a good, easy, portable snack food. One can of Crown Prince, 2 layers, boneless, skinless sardines in water (readily available at Trader Joe's, etc.) offers 3 blocks of protein, around 3 blocks of fat, and a low intake of heavy metals. Plus, it's durable in a backpack or glove compartment and has a long shelf life. Just add a healthy helping of carbs--and down the hatch!
