I have! >>>
I roast turkey without the stuffing like Ang mentioned.
I rub it with some favourite spices and a little oil, then put it in the bag.
I throw in an onion (cut into smileys/bigeyes.gif and a carrot (roughly sliced) for flavour, chop off one of the corners of the roasting bag to let the steam out and roast it according to the recipe.
I love roasting bags!!!
