Sure. Celery has really low calories and peanut butter is high in protein. Just watch out for the calories. I buy the Jiff peanut butter cups on the go. 250 calories for like 3 tablespoons worth. But really great for traveling and yummy with a cut up apple. Try fruit, pretzels, protein bars, and Kellogs had chips that you can have almost 30 chips for 110 cals!
