Preheat oven to 400 degrees. Place the Brussel sprouts, sweet potatoes and cranberries in a bowl. Splash Ramp Dressing on the vegetables and toss to coat them thoroughly. Spread the vegetables on a lightly greased cookie sheet, season with salt and pepper, and roast at 400 degrees for 30 min. or until they are tender and slightly browned (roasting time will vary by oven). Remove from the oven, sprinkle with feta cheese and serve.
