Place chicken breasts in a wide pot or deep skillet, then pour in enough water until chicken is completely submerged in water.
Bring pot to a boil, then reduce to a simmer and cover with a lid. Cook for 10-12 minutes, or until chicken is cooked through.
Remove chicken from the water, then place on a cutting board and either chop the chicken into cubes or shred the chicken with two forks.
Place chopped or shredded chicken into a large bowl and let cool completely.
Once cool, add in all remaining chicken salad ingredients. Mix everything together until well combined.
