Bake walnuts in a shallow pan at 350° for 5 minutes or until toasted.
Bring cranberries, brown sugar, and 1/2 cup water to a boil in a small saucepan over medium-high heat; boil, stirring often, 3 minutes or until cranberries pop. Stir in walnuts, vinegar, and next 6 ingredients; reduce heat, and simmer 20 minutes or until apple and pear are soft. Remove from heat; stir in orange rind. Cover and chill.
