Healthy Snacks For The Children

Ok so I am trying to come up with some yummy, healthy, CHEAP snack ideas for the kiddos...here is some that I have come up with;

• celery w/peanut butter
• apple slices w/peanut butter
• granola bars (I am thinking of doin a TON of homemade. Any recipes?)
• triscuits & cheese (can be cheap when the tricuits are at rock bottom prices)
• string cheese (gotta wait for that sale)

Can anyone help me out and give me some ideas? I am sure alot of mothers out there are curious to see what we come up with.
