Pecan Chicken Salad on Cucumber Slices

1 cup shredded cooked white chicken breast meat
2 teaspoons chopped fresh tarragon
1/4 cup mayonnaise
1/4 cup low fat sour cream
1/4 cup finely diced celery
1/4 cup chopped pecans
coarse kosher salt and black pepper to taste
2 cucumbers (seedless, if possible)

Combine all ingredients except the cucumbers in a bowl. Refrigerate until chilled, if desired.
Slice cucumbers lengthwise and spoon chicken salad onto it, as though it was bread.
