Add the chicken thighs to the bottom of the slow cooker and scatter the sliced bell peppers on top.
In a mixing bowl, whisk together the peanut butter, soy sauce, lime juice, minced garlic, grated ginger, and chicken broth until the sauce is smooth.
Pour the sauce evenly over the chicken and peppers.
Cover and cook on low for 6 hours until the chicken is tender and easy to shred.
Shred the chicken directly in the slow cooker using two forks and stir it into the sauce with the peppers.
Spoon the mixture over cooked rice and sprinkle with chopped peanuts before serving.
