Granola was originally intended as an easy way to sneak more whole grains into the American diet. Today most modern granola isn’t as healthy as you think. Somehow it crossed over into candy bar land with increased refined sugars, unhealthy fats and pieces even dipped in chocolate. But it doesn't have to be that way — you can give your homemade granola a makeover. Store your granola at room temperature in an airtight container for up to one week.
