Sweet potato could to be a very good snack for kids.
sometimes when my daughter is back of school and want something different, I prepare this .
it's a very simple process, boil sweet potato, peel the skin, cut into round circles.
Then shallow fry on the pan, sprinkling little salt and pepper and whatever the spices you like. I have used pepper and salt to keep it simple so take one or two sweet potatoes for 2-3 children or adults, enjoy it with coffee or tea.
