I made this last night and it was so easy, but really good and filling.
3 cups diced cooked chicken, chilled (I never do things in advance, so mine was hot and still good)
1/2 cup diced apple
1/2 cup chopped celery
1/2 cup chopped walnuts
1/4 cup dried fruit (we used cherries. Cranberries would be good too)
3 Tbsp balsamic vinegar
5 Tblsp olive oil
Salt and pepper to taste
Croissants, pita bread or other rolls
Combine all dry ingredients. Combine vinegar, oil, salt and pepper. Pour dressing over other mixture. Chill or serve immediately on the bread.
