Start by chopping the sweet potatoes into 1-2 inch pieces, with the skin on.
Bring a pot of water to a boil, using enough water to have at least 1 inch of water above the sweet potato.
Once boiling, add the chunks of sweet potato to the water, reduce to medium high heat, then slow boil for approximately 15 minutes, or until cooked throughly.
Drain the sweet potatoes with a colander, then add them to your plate.
