Heat the peanut butter in the microwave on high for 20 seconds to loosen it, then stir the honey into it.
Place the granola into a food processor and lightly process to crush up the granola, nuts and raisins.
Peel and cut each banana in half across the middle. Insert a popsicle or chopstick into the cut end of each half-banana. Spread one side of each banana stick with 1/4 of the peanut sauce, then coat liberally with spoonfuls of granola, gently pressing it into the peanut butter.
Eat the bananas right off the sticks, but serve on a plate to catch the crumbs!
