Prepare Your Slow Cooker: Place seasoned chicken in the slow cooker, ensuring it's evenly distributed for consistent cooking throughout.
Mix Your Sauce: In a bowl, whisk together pineapple juice, soy sauce, brown sugar, minced garlic, and ground ginger until well combined, then pour this flavorful mixture over the chicken.
Add Vegetables: Toss in pineapple chunks and thinly sliced red bell pepper on top of the chicken before covering it with a lid.
Set Cooking Time: Cook on low for 5–6 hours or high for 3–4 hours until the chicken is tender and easy to shred.
Thicken Your Sauce: Once cooked, remove the chicken and mix cornstarch with water; stir this into the sauce in your slow cooker and cook for an additional 15 minutes until thickened.
Combine & Serve: Return the chicken back into the pot, coat it well with sauce, cook for another 5 minutes, then serve hot over rice garnished with green onions and sesame seeds.
