Preheat oven to 350°.
Place hazelnuts on a baking sheet. Bake nuts at 350° for 15 minutes, stirring once. Turn nuts out onto a towel. Roll up towel; rub off skins. Coarsely chop nuts, and set aside.
Place a nonstick skillet coated with cooking spray over medium heat. Add quince, and sprinkle with sugar. Cook 15 minutes, stirring frequently or until very brown. Stir in 1/2 cup broth, and bring to a boil. Reduce heat, and simmer, uncovered, 5 minutes or until quince is tender and the liquid nearly evaporates. Add bell pepper, onion, poultry seasoning, and garlic; cook an additional 3 minutes.
Remove pan from heat; stir in 1/4 cup broth, bread cubes, hazelnuts, salt, and pepper. Spoon the quince mixture into a 1-quart baking dish coated with cooking spray. Cover and bake at 350° for 30 minutes.
