If you're on a gluten-free diet, a bag of popcorn is definitely a no-no. Unless it's a bag of Mini Pops ($23)! Technically, the snack is air-popped sorghum grain, so it's completely corn- (and gluten-) free. The tiny grains pop similarly to corn, but don't contain any leftover kernel particles, so you won't find yourself with pieces stuck in your teeth. Munch on a plethora of flavors, from caramel to chili cheese.
