Leeks in Mustard Sauce Recipe

Leeks have a delicious oniony flavor and they are so wonderful in this side dish. The mustard sauce compliments the leeks flavor well and it goes well with many main dishes.—Taste of Home Test Kitchen, Greendale, Wisconsin
TOTAL TIME: Prep: 15 min. Cook: 20 min. YIELD:8 servings

"This is a great recipe, easy and tasty. I served it with roast pork and I'm glad I made extra sauce because that was great on the pork roast too."
