Spread 2 tablespoons peanut butter on the inside of each hot dog bun. Place a peeled banana inside each bun. Cut off the end of the banana if it is too long for the bun. Drizzle the top of each banana with 1 tablespoon of honey. Sprinkle approximately 2 tablespoons of granola on top of the honey. Drizzle with raspberry sauce. Top with diced kiwi.
When packing the sandwich, to keep it from getting soggy make sure to pack the kiwi relish and raspberry sauce separately in small plastic containers. Have your child top the sandwich at lunchtime.
