In the slow cooker
In the slow cooker, add all ingredients except the corn flour and 4 tbsp water for the slurry and the frozen vegetables.
Cook on low for 3-4 hours or high for 2 hours, or until the chicken is cooked.
In the meantime, cook up the required amount of rice or noodles, following the packet instructions.
In the last 20 minutes, add the frozen asian vegetables to the slow cooker. Don't add them too soon otherwise the vegetables will overcook.
Once the chicken is cooked, add the corn flour and water slurry to thicken the sauce. If you like your sauce thicker, add another tbsp of corn flour and water and thicken some more.
Serve over rice or noodles and garnish with toasted sesame seeds if you like.
