Chicken and Brie

I was given a wedge of Brie the other day, and while I didn't have any crackers for it, I wondered what else could be done... Chicken, brie and onion. :)

1 large onion sliced
1 clove crushed garlic
1/4 cup low salt chicken stock (Using a 250ml carton, keeping the rest for below)

1 Wedge of Brie cheese - around 200-250g I guess?
Fresh Sage - oh.. a small bunch, or a teaspoon of dried

4 chicken breast fillets, with a pocket cut into them

In a pot, add the onion, garlic, sage and stock, simmering low until onion has softened.
Remove the rind from the cheese, cut into cubes. Remove the onions from the heat and add the cheese to melt slightly.
Spoon mixture into chicken fillets, secure with a toothpick or skewer. Set into a baking dish. Heat remaining stock in pot that had the onion and cheese and add a tablespoon of cornflour to thicken slightly. Pour over chicken in dish, bake at 180C for around 40 minutes or until cooked.
 Serve with some of the sauce.. and I dunno what to have as a side.. We're having roast taters :P
