Spray a 6 quart slow cooker with nonstick spray. Place the chicken breasts in the bottom of the slow cooker.
Combine the Catalina dressing, apricot preserves, onion soup mix, and Sriracha sauce.
Pour this over the chicken. Cover with the lid and cook on low for 4-5 hours or until the chicken reaches an internal temperature of 165 degrees.
Remove the chicken breast to an ovenproof serving platter and place it in a warm oven. To thicken the sauce mix two tablespoons of cornstarch with two tablespoons of cold water. Whisk this into the sauce and turn the slow cooker to high. Cover with the lid. It should take 5-8 minutes or so for it to thicken. Spoon the sauce over the chicken breasts, garnish with fresh chopped parsley, and serve.
Notes
* 1/2 teaspoon of crushed red pepper flakes may be used instead of Sriracha sauce.
