Place the chicken thighs in the slow cooker. In a separate bowl, whisk together honey, soy sauce, ketchup, minced garlic, ground ginger, and black pepper. Pour the sauce over the chicken, ensuring it is well coated.
Cover the slow cooker and cook on low for 6-7 hours or on high for 3-4 hours, until the chicken is tender and easily shredded.
About 30 minutes before serving, cook the egg noodles according to package instructions. In the last 15 minutes of cooking, add the broccoli florets to the slow cooker.
Once the chicken is done, shred it in the slow cooker using two forks and stir to combine with the sauce.
Drain the egg noodles and add them to the slow cooker, mixing everything together until the noodles are coated in the sauce.
Serve hot, garnished with sliced green onions and sesame seeds if desired.
