In a large mixing bowl, whisk together peanut butter, coconut milk, soy sauce, lime juice, minced garlic, grated ginger, brown sugar, and sriracha until smooth.

Place chicken breasts or thighs into the slow cooker and pour the peanut sauce over, ensuring the chicken is well-coated.

Cover and cook on low for 6-8 hours or high for 3-4 hours until chicken is tender.

Once cooked, shred the chicken with two forks or serve whole, mixing the sauce well.

Serve in bowls topped with crushed peanuts, cilantro, and lime wedges.
