Many chicken salad recipes feature almonds, which are so expensive that I rarely buy them. However, peanuts are very reasonably priced at Asian markets. Stock them in your pantry, as they're often a good substitute for more expensive nuts.
BBQ Chicken Chopped Salad with Creamy Avocado Dressing - sounds wonderful! - very good and very filling, however we used a "guacamole ranch" dressing by Wishbone brand because it was costly to make the avocado dressing.
