Your not being a fan of peanut butter is really going to hurt you as far as cheap/portable protein options. Let's see. ½ cup of cottage cheese and ½ cup of whatever fruit you like? I'd say beef jerky, but that tends to get pretty expensive. A hard-boiled egg or two, maybe? Low fat chocolate milk? Special K makes protein shakes as well, though I guess there would be cheaper generic options for that as well.
