Stretch Island Fruit Co. - Original Fruit Leathers
I loved these as a kid (and am probably gonna buy some more now!) Stretch Island has been making their 'Fruit Leathers' for years - simple, flat fruit bars made out of, well, fruit. Smooshed fruit. Sure, they throw in some concentrate of various fruits to keep it together (so it's not 100% raspberry, for example), but they're always tasty, cheap, around 45 calories per serving and count as 1/2 dose of your daily fruit needs as well. Perfect for the lunchbox or afternoon snack. You can buy packs of 30 directly on their site or use their store locater. I like raspberry, strawberry and apricot, but they have some neat blends as well.
