What to make for a big family reunion? This gelatin salad is an easy choice. It's easy to tote, and it is light and refreshing. For the best flavor, toast the nuts before adding them.
In a medium saucepan, combine undrained pineapple and sugar; heat to boiling. Stir in gelatin until dissolved. Stir in cream cheese until melted and well combined. Remove from heat. Transfer to a large mixing bowl.
Chill about 1 hour or until mixture is slightly thickened. Stir in chopped apple and nuts. Fold in dessert topping. Transfer mixture to a 2-quart baking dish or 1-1/2-quart bowl or mold. Cover and chill at least 4 hours. To serve, cut into squares, serve in bowl, or unmold onto serving plate. If desired, garnish individual servings with orange sections and grapes. Makes 9 to 12 side-dish servings.
