Sweet Hawaiian Crockpot Chicken:

Preparation: Place the chicken breasts in the crockpot. In a mixing bowl, combine pineapple juice, soy sauce, honey, ketchup, garlic, ginger, and red pepper flakes. Mix well until the honey is fully dissolved.
Cooking: Pour the sauce mixture over the chicken in the crockpot, ensuring the chicken is evenly coated. Cover and cook on low for 4-5 hours, or until the chicken is tender and cooked through.
Thickening the Sauce: In a small bowl, whisk together water and cornstarch until smooth. Stir the cornstarch mixture into the crockpot during the last 30 minutes of cooking. This will thicken the sauce to a desirable consistency.
Serving: Once cooked, remove the chicken from the crockpot and slice or shred it, as desired. Serve the chicken over steamed rice or quinoa, spooning the sweet Hawaiian sauce over the top. Garnish with sliced green onions and sesame seeds for added flavor and texture.
Storage: Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or on the stove, adding a splash of water or broth to loosen the sauce if needed.
