This chicken salad is refreshing and totally fit for summer. The recipe comes from food writer Debora Robertson, who says: “I have been making this salad, and versions of this salad, for decades, ever since I shared a flat with a Southern Belle from Virginia in my second year at university. Once she made it for a lunch with some fellow Americans. One took a bite and declared ‘Mary Martha, I believe you must have been to a lot of debutante lunches this summer’. Whether you’re a southern debutante or not, it’s entirely appropriate for the season.”
