Huntsmans Chicken

Ingredients
1 large onion, diced
2-3 cloves garlic, crushed
1 cup chopped mushrooms
1 400g can diced tomatoes in juice
400g skinless boneless chicken breasts

2 tsp instant chicken stock powder
1/4 cup boiling water
1/4 cup red or white wine
1-2 tsp sugar or sugar replacer
2 Tbsp tomato paste

1/2 cup sliced olives
2 Tbsp chopped parsley
2 Tbsp chopped fresh basil, if available

Method
Turn a fairly large slow cooker to LOW. Place onion, garlic and mushrooms in the cooker and mix together.
Spoon tomatoes and their juice evenly over the onion mix.
Place whole chicken breasts on top.
Combine next 5 ingredients in a measuring cup or other small container and pour over chicken.
Cover and cook on LOW for about 8 hours or HIGH for about 4 hours.
The chicken should be soft enough to shred with a pair of tongs or fork without removing from the crockpot.
Stir in olives, parsley and basil, and serve.

I think this is based on a Simon/Alison Holst recipe
