A quick look and I can't find it on the web!
Sadly, my mother has forgotten stuff she used to cook.
There was this leg of with creamy coffee sauce I had asked her years ago for a coffee addict who wanted to know, but she couldn't remember as it had been a while.
I did find some versions listed now, including one under "Swedish," which should be like it as the relative she got that from was of Norwegian background (born here).
I had to stop looking as I was getting hungry.
My ma used to make tuna casserole too, is that with the ziti and green peas?
