A delicious twist on the classic, this dish goes above and beyond with four colors of potatoes, including the purple potato which is not only rich in heart disease-fighting anthocyanin but also was once reserved exclusively for the Incan kings in Peru.

3 red potatoes, cut into 1-inch pieces
1 sweet potato, peeled, cut into 1-inch pieces

1 teaspoon Dijon mustard
2 tablespoons chopped chives teaspoon ground black pepper
