Wrap the sweet potato in foil and place in the oven. If you cannot find a whole sweet potato close to your serving size, then simply cut the sweet potato into small pieces, measure them to ensure your serving size portion, and bake them on a baking sheet lined with aluminum foil. Bake for about 45 minutes, depending on the size. If they are cut in chunks, then bake for only 25-30 minutes.
Cut flank steak into very small pieces. Season with your choice of seasonings.
