Instead of grabbing a bag of store-bought chips, try making your own baked version at home. Michael Pollan says that eating junk food on the occasion is OK, as long as you make it at home, rather than buy it at the store. Pollan explains, "The fact that labor has been removed from special occasion food has made us treat it as everyday food. One way to curb that and still enjoy those foods is to make them."
To make a homemade, nutrient-rich sweet potato chip: slice sweet potatoes thinly on a mandolin slicer, toss the slices in one teaspoon of olive oil, lay them out on a cookie sheet, sprinkle them with salt, and bake at 400 degrees for 20-25 minutes, flipping once. This snack will put you at 108 calories, but it will help quench your chip craving, plus you'll get over 400 percent your daily value of vitamin A.
