My five year old has just started pre-competitive gymnastics, which is twice a week at 4:30 for 90 minutes each. Last week, she said she was hungry even though she ate her lunch and snack. Any ideas on what I can pack for her for her 3:30 snack that's shelf stable and with a good amount of carbs and protein? I really want to make sure she gets enough since she is underweight as is (as in off the scale altogether). She likes smoothies, but only if they're freshly blended (which is why I can't just pack her a smoothie), and her school doesn't allow nuts. I already pack her cheese and fruit with her lunch and don't want her to get sick of the same thing.
