Popcorn
This is perhaps the most inexpensive, healthiest (unless you drench it is butter like me) snack possible, which makes popcorn so hot right now. Don’t buy the microwave kind (sorry, Boy Scouts); and heaven forbid that you purchase the pre-popped kind (stale, over-priced).
A 1 lb. bag of kernels — which lasts us months and months — costs under $3. Buy a maker like ours for cheap from Amazon or just pop it on the stovetop with a little oil. Salt&pepper, butter, cinnamon&sugar, taco seasoning (mixed in with melted butter) are some of the many, many different ways to spice it up. If you wanna be soopahfancy, use this recipe from SmittenKitchen.
