I was in woolies the other night at got a whole cooked chicken for $3.80. I popped in in the slow cooker with a carrot, the top of the celery ( leafy part), a stock cube, some onion, garlic and herbs ( so prob $6 in total) covered with water and cooked it for half a day to get a nice stock.
Then I got a bowl and stained and filtered the juice and the chicken.
I then picked out the chicken bits from the strainer, put 2 cups of fresh vegies in a pan with some butter, when butter was melted added some flour then 2 cups of the stock, mixed then added a cup of milk, add the chicken and i had a chicken pie mix. So for aprox $10 i made 4 mini lunch pies and 1 big dinner pie and froze the rest of the stock.
