Preheat oven to 325°.
Prepare rice according to package directions, omitting fat and seasoning packet. Set aside.
While rice cooks, place bread in a food processor; pulse 15 times or until fine crumbs measure 1/2 cup. Add 1 teaspoon butter to processor; pulse until combined. Add cheese to processor, and pulse until combined.
Heat a large skillet over medium-high heat. Add 2 teaspoons of butter, onion, garlic, and mushrooms; sauté 7 minutes or until onion is tender. Stir in turkey and next 7 ingredients (through pepper). Add cooked rice; stir.
Spoon rice mixture into a 1 1/2-quart casserole coated with cooking spray. Sprinkle with breadcrumb mixture. Bake at 325° for 30 minutes or until golden brown. Serve with cranberry sauce.
