Roasted Beet Salad with Walnuts, Goat Cheese & Honey-Dijon Vinaigrette

Preheat oven to 425°F. Wipe or scrub beets clean then trim stems down to one-inch (leave "tails" on). Place beets on a large piece of foil; drizzle with olive oil, then wrap foil around them to form a neat packet. Roast directly on rack in middle of oven until tender, about 1 hour. Test for doneness by piercing the largest beet with a knife. If it enters easily, it's done. Unwrap beets and let sit until cool enough to handle. Use your hands or a paring knife to peel skin, then cut into ½-inch dice (I usually do this right on the aluminum foil but you can also use a stain-proof cutting board or plate). Set aside. In a small bowl, whisk together the honey, Dijon mustard, red wine vinegar, shallots, salt and pepper. Whisking constantly, slowly add the oil in a steady stream. (Alternatively, add all your ingredients to a jar, cover with lid, and shake vigorously to blend.) Taste and adjust seasoning if necessary. Place the greens in a large bowl, drizzle with about half of the vinaigrette and toss to combine. Add as much of the remaining vinaigrette as desired and toss again. Divide greens onto plates, then sprinkle with beets, walnuts and goat cheese. (The reason you don't just mix it all together in a salad bowl is that the beets would cause the whole salad to turn pink.) Serve immediately.
