01 - Pat chicken thighs dry with paper towels. Season both sides generously with salt and black pepper, rubbing the seasoning into the meat.
02 - Layer the sliced bell pepper, onion, carrot, minced garlic, and grated ginger evenly across the bottom of the slow cooker insert.
03 - Arrange the seasoned chicken thighs on top of the vegetable layer, ensuring they are not overlapping for even cooking.
04 - In a medium mixing bowl, whisk together the peanut butter, soy sauce, chicken broth, honey, rice vinegar, lime juice, sriracha if using, and sesame oil. Whisk vigorously until completely smooth and emulsified, about 1-2 minutes.
05 - Evenly pour the peanut sauce mixture over the chicken and vegetables, ensuring all pieces are coated.
06 - Cover with the lid and cook on low setting for 5 hours, or until the chicken registers 165°F internally and shreds easily with a fork.
07 - Carefully remove the chicken from the slow cooker and transfer to a cutting board. Use two forks to shred the meat or cut into large chunks. Stir the sauce in the cooker well to incorporate any browned bits, then return the chicken to the sauce and toss to coat thoroughly.
08 - Serve hot over steamed jasmine rice. Garnish generously with chopped roasted peanuts, fresh cilantro, and additional lime wedges for squeezing.
