Dear Nancy,
This is a recipe that I got last year from your site but can't tell you who came up with this fantastic recipe. This person who sent it in should have credit. I would call it a dessert instead of a salad but I wanted to be sure that your followers have it in their files.

Grape Salad

3 lbs seedless grapes (red or green or a combination)
1/4 - 1/2 cup sugar (adjust to taste)
8 oz sour cream
8 oz cream cheese (softened)
1 tsp vanilla
1 cup walnuts or pecans, chopped
1/2 - 1 cup light brown sugar (adjust to taste)

Wash and stem grapes; drain. In large mixing bowl, combine sugar, sour cream, cream cheese, and vanilla till smooth. Pour over grapes; mix till thoroughly combined. In separate bowl, mix nuts and brown sugar together. (I use the maximum amount of brown sugar, because I love the mix of the flavor with the sweet/sour of the grapes.) Pour grape mixture into serving dish; sprinkle top with sugar and nut mixture. Chill and serve. This recipe makes a very large portion (suitable for a family gathering of 20 or possibly more, depending on appetites). Recipe may be halved. Keeps well in refrigerator for several days (if it lasts that long).
