When chicken salad comes to mind, I always think of a mayonnaise-bound concoction (not that I don’t enjoy that). But this chicken salad recipe, from Alison Lewis’s new book 400 Best Sandwich Recipes (Robert Rose) updates an old favorite with a fresh, bright-flavored, colorful spin. There’s no added salt in this recipe, because the feta and Kalamata olives add plenty of salty kick. If you don’t want to buy a whole jar of olives, look for Kalamatas that you can purchase by the pound at the supermarket salad bar, olive bar or deli case. Lewis recommends using leftover grilled chicken or rotisserie chicken. Or, to change it up, sub chopped, cooked shrimp for the poultry. Use whole wheat pita bread, if you can find it.
