Colcannon is a classic Irish side dish that couples mashed potatoes with cabbage or kale. We use low-fat milk instead of the more traditional cream-and-butter combination for a lighter, but no less delicious, profile. Serve this healthy side with lamb, salmon or roast chicken any time of year--there's no need to save it just for St. Patrick's Day.
To make ahead: The potatoes can be prepared up to 1 hour ahead and kept warm, covered, over a larger pan of barely simmering water.
