1In 1-quart saucepan, cook bacon and onion over medium-high heat, stirring frequently, until bacon is cooked and onion is tender. Drain bacon and onion. In same saucepan, heat water and bouillon granules to boiling. Stir in bulgur; remove from heat. Cover and let stand 15 minutes. Stir in bacon mixture, zucchini, mushrooms and thyme.
2Heat oven to 350°F. Fill body cavity of hen with stuffing. Fasten opening with skewer. Place hen, breast side up, on rack in shallow roasting pan. Place meat thermometer in thigh muscle so tip does not touch bone. Brush with some of the butter.
3Bake uncovered 1 hour to 1 hour 15 minutes, brushing occasionally with remaining butter, until juice of hens is clear when thickest pieces are cut to bone (at least 165°F).
4Remove stuffing from body cavity. Cut hen in half along backbone from tail to neck with kitchen scissors. Serve each hen half with stuffing.
