In a bowl, whisk together honey, soy sauce, minced garlic, grated ginger, sesame oil, and crushed red pepper flakes until well combined.
Lay the chicken thighs at the bottom of the slow cooker.
Pour the honey garlic mixture over the chicken, ensuring each piece is well coated.
Cover and cook on low for 6-7 hours or on high for 3-4 hours until the chicken is cooked through and tender.
About 30 minutes before serving, add the broccoli florets and bell pepper slices to the slow cooker. Stir gently.
Before serving, remove the chicken from the slow cooker and set aside. Stir in the cornstarch mixture into the remaining sauce, and cook on high for an additional 15 minutes with the lid on to thicken.
Once the sauce has thickened, use two forks to shred the chicken.
Add the shredded chicken back to the slow cooker and stir to combine with the thickened sauce and vegetables.
Notes
Serve over steamed rice or quinoa, and garnish with sesame seeds and chopped green onions for a pop of color.
