Grill yourself a whole bunch of chicken early in the week and take what you need for the day. As for easy, nutritious snacks, I always have on-hand pumpkin seeds, sunflower seeds, almonds, canned tuna or salmon... I also have (low-sodium) lentil or black bean soup. Don't worry about the fat content of seeds, nuts, etc...these are healthy fats...your body needs them. I also keep a tub of protein powder at work when I don't have whole food lying around or I get lazy.
