Separate wings at joints and discard tips. In slow-cooking pot, combine wings, broth, celery, and salt. Cover and cook on low for 4 to 6 hours or until tender. Drain, saving 1 1/2 cups broth for sauce. In large skillet, combine cornstarch, brown sugar, 1 1/2 cups broth, vinegar, soy sauce, and chili sauce. Cook and stir until thick and clear. Stir in green pepper and pineapple; simmer for 2 minutes. Add drained, cooked wings. Bring to simmer. Serve over rice.
