In a large skillet cook turnips in butter over moderate heat, stirring occasionally, until almost tender and golden on the edges, about 10 minutes.
Stir in Panko bread crumbs, mint, zest, salt and pepper to taste. Cook, stirring occasionally, until turnips are tender, about 5 minutes. Plate and enjoy!
