Place the chicken in the bottom of your slow cooker.
In a medium mixing bowl whisk together the soy sauce, honey,
tomato purée, chilli paste, garlic, and rice vinegar.
Pour over the chicken.
Cover and cook on low for 4-5 hours or high for 2-3 hours,
until the chicken is cooked through. If you are available, flip the
chicken over halfway through to coat both sides. (If not, don’t stress;
it will still be tasty.)
Remove the chicken to a plate and let cool slightly.
Whisk the cornstarch into the slow cooker cooking liquid.
Cover and cook on high for 15 minutes, until the sauce thickens slightly,
stirring occasionally. If you’d like the sauce particularly thick, you can
cook it for a full 30 minutes in the slow cooker or reduce it on the hob.
Shred the chicken with two forks and place it in the slow cooker.
If you reduced the sauce on the stove, add it back to the slow cooker now.
Stir to coat the chicken with the sauce.
Serve over rice, sprinkled with spring onions and sesame seeds.
