Begin by cutting the chicken thighs into bite-sized chunks. Season the pieces generously with salt and pepper to enhance their flavor.
In a medium mixing bowl, whisk together the sweet chili sauce, soy sauce, minced garlic, freshly grated ginger, rice vinegar, and sesame oil until the ingredients are thoroughly combined and a smooth sauce forms.
Place the seasoned chicken pieces into the slow cooker. Pour the prepared sauce mixture over the chicken, ensuring all pieces are well coated. Gently stir to distribute the sauce evenly.
Layer the sliced red and green bell peppers along with the sliced onion on top of the chicken in the slow cooker. This will allow the vegetables to infuse their flavors into the dish as it cooks.
Secure the lid on the slow cooker and set it to cook on low for 6-7 hours or on high for 3-4 hours, until the chicken is tender and reaches an internal temperature of 165°F (74°C).
Once the cooking time is complete, use two forks to shred the chicken right inside the slow cooker, mixing it well with the sauce and vegetables. This will create a flavorful, cohesive dish.
Taste the concoction and adjust the seasoning as needed, adding extra salt or freshly ground pepper according to your palate.
Notes
Serve over steamed jasmine rice or quinoa, garnished with green onions and sesame seeds.
