Chicken-rice salad

This tangy, healthy salad is delicious on any bread item. We had it on rolls once, and in hollowed-out tomatoes another time.

Mix together:

3 cups chopped or shredded cooked chicken
1 diced apple
1 can water chestnuts
1/2 cups scallions (I left this out)
1 cup red grapes, halved
1 cup green grapes, halved
1/2 cup chopped celery
3 cups cooked wild rice

Toss with this dressing:

1 cup plain yogurt
1 tablespoon lemon juice
1 teaspoon mustard
1 teaspoon dill
salt and pepper to taste
