If you don't have any cooked chicken on hand, pick some up at the supermarket. Look for refrigerated or frozen chopped, cooked chicken or buy a deli-roasted chicken. It will yield 1-1/2 to 2 cups of boneless chopped meat. If you like, you can cook your own. Place 1-1/4 pounds of skinless, boneless chicken breasts and 2 cups water in a large skillet. Bring to boiling; reduce heat. Cover and simmer for 12 to 14 minutes or until chicken is no longer pink (170 degrees). Drain well. Chop chicken. 1-1/4 pounds of boneless breasts with give you about 3 cups cubed cooked chicken.
