Roast Leg of Lamb on a Bed of Potatoes and Wilted Greens

Preparation Preheat oven to 350°F. Trim all fat and silver skin from lamb. Cut small slits all over lamb with a sharp knife and put a slice of garlic and a pinch of thyme and rosemary into each slit. Peel potatoes and thinly slice about 1/16 inch thick with a mandoline or other manual slicer, then toss with 4 tablespoons oil, 1 1/2 teaspoons salt, and 1/2 teaspoon pepper in a large bowl. Spread potatoes evenly in a 17- by 12- by 2-inch casserole or roasting pan. Put lamb on top of potatoes, then rub with honey and sprinkle with remaining 2 1/2 teaspoons salt and 1/2 teaspoon pepper. Roast lamb in middle of oven 1 hour, then drizzle with 1 tablespoon oil. Continue to roast until an instant-read thermometer inserted into thickest part of lamb (do not touch bone) registers 135°F for medium-rare, 30 to 45 minutes more. Let lamb stand, covered loosely with foil, 15 minutes. While lamb stands, heat remaining 2 tablespoons oil in a 4- to 6-quart heavy pot over moderately high heat until hot but not smoking, then sauté minced garlic, stirring, until fragrant, about 30 seconds. Add a handful of greens and sauté, tossing with tongs, then add more greens as preceding ones wilt and sauté until all greens are wilted and tender, 5 to 6 minutes total. Season with salt and pepper. Transfer lamb to a cutting board and carve, then serve with potatoes and greens.
