I heard someone once say she liked to bake a bunch of sweet potatoes at one time, then keep them in the refrigerator as snacks throughout the week. So I tried it and had several on hand. Mathis eats a peanut butter sandwich every day - sometimes with jelly, sometimes with honey, sometimes with banana - so I had the idea of mashing a cold sweet potato on the peanut butter, then drizzled it with some agave syrup and served it to him. He loved it. Still sweet, but this way he gets added fiber and beta carotene. Simple and plant strong.
