I would definitely say LC tortilla wraps---tuna, egg salad, turkey...whatever she likes
celery and cream cheese, even natural p-nut butter.
LC yogurt
hard boiled eggs
cheese and pepperoni chunks
I would still add some lower carb fruit for her too.
salsa and homemade LC tortilla chips
salads if she likes them--chef salads would work great but a lot of kids dont like them.
SF jello
for a treat SF pudding
Even use LC whole wheat or rye bread if she really likes sandwiches
