Good Morning,
Chicken and tuna salad are quite subjective. I like my chicken salad with: diced chicken breast, fresh dill herb, freshly ground blk pep, smoked paprika piquant, broken ( not powdery ) walnuts, spring scallion, home made ali oli and on a warm toasted baguette.
Tuna salad, quite similar however, with onion, diced celery and instead of the ali oli, I blend with a slow stream of olive oil which gives it a paste - dip texture or mousse like however, thicker and freshly Italian parsley herb.
Thanks for posting your recipe, I shall try it out for an office lunch.
Margcata.
