Make the sauce by combining the soy sauce, honey, tomato paste, sriracha, sesame seed oil, minced garlic, rice wine vinegar, and 2 tbsp of water in a small bowl.
Place the chicken thighs in the pot of your slow cooker and pour the sauce over them.
Cook on low for 4 hours or high for 2-3 hours.
Once cooked, grab two forks and shred the chicken thighs.
Make a slurry by combining the remaining 2 tbsp of water with the cornstarch. Add this to the slow cooker and cook for an additional 5-10 minutes or until the sauce thickens. Serve over freshly cooked rice, quinoa, or mashed potatoes with sesame seeds and sliced green onions on top.
