Can't believe you guys are trading processed snacks by the water fountain like it's the stock exchange. LOL remember to eat an apple or something today. Keep it somewhat healthy, kids!
Did you guys forget about nuts? Almonds, peanuts etc are full of protein, plus they're just great snacks to have lying around. But don't forget about portion sizes, they are high in fats even though it's the good kind. Also check out some protein-rich grains like spelt and teff.
