Heat oil in large nonstick skillet on medium-high heat. Add mushrooms; cook and stir until mushrooms are tender and liquid is cooked off. Cool slightly.
Meanwhile, prepare stuffing as directed on package, reducing water to 1 cup and butter to 2 Tbsp. Add mushrooms and cheese; mix lightly.
Place lamb, cut-side up, on cutting board; press to flatten. Spread with stuffing mixture. Roll up, starting at one long side. Tie closed in several places with kitchen string. Place in 13x9-inch baking dish. Whisk remaining ingredients until blended; pour over lamb.
Bake 1 hour 20 min. or until lamb is medium-rare doneness (150°F). Remove from oven. Cover with foil; let stand 10 to 15 min. or until medium doneness (160°F).
How to Purchase Lamb
Look for lamb that is pinkish red and has a velvety texture. Dark red meat usually indicates the meat is older.
Serve with a side of greens such as swiss chard, spinach or asparagus or veggies such as zucchini, yellow squash and onions.
