In a bowl, mix the cheeses and Wholegrain Mustard
together.
Cut a slit into the side of each chicken breast, then stuff
with the mustard mixture.
Stretch the bacon rashers by pressing the back of a knife along
the rasher, then wrap 2 rashers around each stuffed chicken breast
just firmly enough to hold the parcel together.
Season, and place in a lightly oiled shallow casserole dish,
cook in the centre of the oven for 20-25 mins.
