This is an all time fave in our house too, cooked probably 1/wk eaten with salad and corn on the cob in summer, or mash and steamed veg in winter...

Slow Cooker Chicken with BBQ sauce

1-1.5kg Chicken (whole or legs)
1 onion
4 tbsp Tomato sauce
2 tbsp vinegar
2 tbsp mango chutney chopped
1 tsp french mustard
1 tsp caster sugar
1 tbsp worstershire sauce

Brown the chicken in a frypan with some oil. Transfer to the slow cooker. Add the other ingredients to the frypan and bring to the boil. Pour over the chicken and cook on high for 4 1/2-5hrs, basting occaisionally.

**I don't put any of it into the fry pan. It all goes into the slow cooker straight away. I have also made it without the chutney, sometimes replacing it with some orange marmelaide, or not replacing at all. I haven't made it with a whole chicken, I use legs all the time, they turn out really yum!
