Humble veggies…cabbage, potatoes and onions cooked and mashed. Colcannon is a budget lover’s dream!
The cooked colcannon keeps up to 4 days in the refrigerator. Cover to keep it from drying out. Reheat, covered, in the microwave at 50% power until heated through. Or heat in oven, covered, at 350℉ until heated through, about 15 minutes.
