Creating this Slow Cooker Sweet Chili Chicken is simple when you follow these straightforward steps:

1. Prepare Chicken: Start by placing the boneless, skinless chicken thighs at the bottom of the slow cooker.

2. Mix Sauce: In a separate bowl, combine the sweet chili sauce, soy sauce, rice vinegar, minced garlic, and minced ginger. Mix well.

3. Add to Chicken: Pour the sauce mixture over the chicken thighs in the slow cooker, ensuring they are well-coated.

4. Add Vegetables: Layer the sliced bell peppers and onions on top of the chicken for added flavor and texture.

5. Season: Sprinkle the black pepper and salt over all the ingredients for enhanced taste.

6. Set Slow Cooker: Cover and cook on low for 6-7 hours or on high for 3-4 hours, depending on your schedule.

7. Check for Doneness: Once cooked, check that the chicken reaches an internal temperature of 165°F (75°C).

8. Shred Chicken: Use two forks to shred the chicken in the sauce. Mix everything until the chicken is well coated.

9. Garnish: Serve the chicken topped with optional garnishes like sliced green onions, sesame seeds, or cilantro for added flavor.

10. Enjoy!: Serve immediately, either on a bed of rice, in lettuce wraps, or as a filling in sandwiches.
