Carol's Chicken Salad

Found this on allrecipes and I definitely want to make it again. Very unique chicken salad flavor. I LOVE water chestnuts ;)

Ingredients
1/2 cup mayonnaise
1/2 teaspoon salt
3/4 teaspoon poultry seasoning
1/4 teaspoon onion powder
1/4 teaspoon garlic powder
1/4 teaspoon ground black pepper
1 tablespoon lemon juice
3 cups diced, cooked chicken breast meat
1/2 cup finely chopped celery
1/2 cup chopped green onions
1 (8 ounce) can water chestnuts, drained and chopped
1 1/2 cups diced Swiss cheese
1 1/2 cups halved green grapes

Directions
In a medium bowl, whisk together the mayonnaise, salt, poultry seasoning, onion powder, garlic powder, pepper, and lemon juice.

In a large bowl, toss together the chicken, celery, green onions, water chestnuts, Swiss cheese, and grapes. Add the mayonnaise mixture, and stir to coat. Chill until serving.
