If you want a quick snack or dessert to make in 5-10 minutes, consider making these dessert quesadillas. They satisfy your sweet tooth and are simple to make. I learned this from a kids' cookbook from Williams-Sonoma years ago, and have loved making it anytime since if I have a spare tortilla laying around.
You can also drizzle honey and add granola if you want to kick the recipe up a notch. And really, you can mess around with it - swap the bananas for raspberries or strawberries, and it would be a quick faux crepe!
