My favorite way to prepare sweet potatos:

Peel your sweet potato & then cut it into thick slices.

Coat in olive oil or melted butter and put it in a 375 degree oven on a
cookie sheet until the pieces are soft and carmelized.

Put the slices in a bowl & add a little more butter, some cinnamon,
some nutmeg & a little salt. If you want to add a little more
sweetness, some maple syrup is also good.

Smush it a little with a fork and call it done.
