Pumpkin-Cornbread Stuffing

Place bread cubes in bowl; set aside. Spray nonstick skillet with olive oil spray; place over medium heat. Add celery, onions, 1/2 teaspoon salt, and 1/8 teaspoon pepper; cook, covered, stirring occasionally, until translucent, about 10 minutes. Remove cover, and add 1 tablespoon water. Cover, and cook 5 minutes more. Transfer vegetables to bread cubes.

Wipe out skillet, and respray. Place over high heat, and add mushrooms, remaining 1/2 teaspoon salt, and remaining 1/8 teaspoon pepper. Saute, stirring frequently until golden brown, 4 to 5 minutes. Transfer to onion-bread cube mixture.

Heat oven to 350 degrees. Spray two 9-by-13-inch baking dishes with olive-oil spray; set aside. Toss remaining ingredients with onion-bread cube mixture. Transfer to prepared baking dishes; spray tops with olive oil spray. Bake until heated through and crusty on top, about 35 to 40 minutes.
