I have made this several times and it's dead easy. If you have overnight guests, what could be easier for breakfast? I've made it on special occasions, too, such as Easter morning and Christmas morning, etc. This recipe comes from the Best of Bridge series.
This is surprisingly good despite the fact that it has canned gravy. You would never know it. I often add a couple of carrots on top of the potato so that I have a complete meal in one dish. Delicious with some nice crusty bread.
I got this recipe from a friend and since I had the blueberries on hand, I decided to make it right away. The cake came out wonderful, and the topping was so nicely baked on top. You have to try this one. I think you could probably use a different berry if you prefer.
