1kg diced chicken breasts
1 tin crushed tomatoes
1 onion, finely diced
1 tablespoon yellow mustard seeds
3 tablespoons soy sauce
3 tablespoons sherry
3 tablespoons brown sugar
2 tablespoons tomato paste (optional)
Mix together all ingredients (except chicken).
Put chicken in slow cooker, then cover with sauce.
Cook on slow/low for 8 hours, or high for 6 hours.
this was originally one from the EB slow cooker book so i'm not sure who to give credit to! the version above is geoff's version which he made today, with a change to the quantity of chicken as 500g wasn't enough either for the sauce or for the family (let alone leftovers!)
i think it would also be nice with some sour cream mixed through.
