In a bowl, mix together the soy sauce, honey, rice vinegar, minced garlic, grated ginger, and sesame oil until well combined.
Place the chicken thighs in the crockpot and pour the teriyaki sauce mixture over them, ensuring the chicken is well-coated.
Add the sliced bell peppers and broccoli florets on top of the chicken.
Cover the crockpot and cook on low for 6-7 hours or high for 3-4 hours, until the chicken is cooked through and tender.
Once cooked, remove the chicken from the crockpot and shred it using two forks.
In a small bowl, mix the cornstarch and water to create a slurry. Pour this into the sauce remaining in the crockpot and stir well to thicken the sauce.
Return the shredded chicken to the crockpot, mix until well combined, and let it sit for an additional 15-20 minutes to absorb the flavors.
Serve the teriyaki chicken over a bed of steamed rice or cauliflower rice, drizzled with the thickened sauce.
Garnish with sesame seeds and sliced green onions before serving.
Notes
Serve over steamed rice or cauliflower rice for a low-carb option.
