Blueberry Salad

2 boxes strawberry gelatin
2 cups boiling water
1 can blueberry pie filling
1 can crushed pineapple (plus juice)
1 8 oz. cream cheese
1/2 cup sugar
1 cup sour cream
1 tsp. vanilla
1/2 cup chopped walnuts

In a 9 x 13 pan, mix gelatin, water, blueberry pie filling & crushed pineapple with juice together. Chill until firm. Top with a mixture of the cream cheese, sour cream, sugar & vanilla. Sprinkle walnuts on top. (This is a good jello salad even without the topping.)
