I made chicken matzo ball soup recently and used only the dark meat in that so I had the breasts left and used them in this recipe.
2 chicken breasts diced
½ cup mayonnaise
2 celery stalks diced
1 carrot chopped or grated
Pinch onion powder
Pinch white pepper
Dice cooked chicken breast. I like it diced fine. Dice Celery fine. You can dice your carrots as I have done above but I prefer to grate the carrot instead as I find the carrot too crunchy other wise.
Place the chicken in a bowl with celery, carrot, mayo, and spices. Mix well. Serve on saltines or on a sadwich.
Cover with plastic wrap and refrigerate leftovers.
