Put the chicken in a large pot and fill with cold water. Add one bay leaf and sprinkle the surface of the water with grill seasoning or seasoned salt. Bring to a boil and then lower the heat and simmer until the chicken is cooked through.

Drain and run under cold water to cool off.

Transfer cooled chicken to a food processor and pulse to chop the meat, cutting the meat into smaller pieces, if needed, to fit (you may need to work in batches). Transfer the chopped chicken to a large bowl and use the food processor to chop the pickles, eggs, onion and celery.

Stir in enough Miracle Whip to bind, and refrigerate.
