The Government of Alberta distributed this recipe (among others) at a conference I attended in Calgary some years ago. It is Mmmm, Mmmm Good, and is wonderful company fare. I find that the sauce tends to thicken quite a bit while baking, so I usually add a bit more water during the process. I would also recommend doubling the sauce (amounts given are from the original recipe). Twice-baked potatoes and seasoned fresh green beans make it a truly outstanding meal (along with fresh dinner rolls, of course). Hope you enjoy it.
