Creating your Slow Cooker Sweet and Sour Chicken Thighs is a straightforward process. Just follow these easy steps:

1. Prepare the Chicken: Season the chicken thighs lightly with salt and pepper.
2. Layer the Ingredients: Place the sliced bell peppers, onion, and pineapple chunks at the bottom of the slow cooker.
3. Add the Chicken: Lay the seasoned chicken thighs on top of the vegetables and pineapple.
4. Mix the Sauce: In a small bowl, combine the sweet and sour sauce, soy sauce, garlic, and ginger. If you prefer a thicker sauce, mix in cornstarch at this point.
5. Pour the Sauce: Pour the sauce mixture evenly over the chicken thighs.
6. Cook: Cover the slow cooker and set it to cook on low for 4-6 hours or high for 2-3 hours, until the chicken is tender.
7. Finish and Serve: If you used cornstarch, stir it in 30 minutes before serving to thicken the sauce. Serve the chicken and sauce over cooked rice.

These clear steps ensure you can create this dish effortlessly while still allowing for your own personal twists.
