I got this recipe from a church cookbook that was compiled by the ladies of the church using their favorite family recipes. I make it often and my family loves it. It is a break from the usual vegetarian loaf recipes and easier to take to potlucks etc. You can take the sauce with you in a tupperware container and add it just before you put it in the oven. I recently tried this a different way with the sauce and it was delicious. I sliced about 5 very large white button mushrooms, finely diced half a large onion and then sautéed them together until cooked down and soft. Then, I drained them on paper towels. After that, I folded them into the soup/sour cream/ milk mixture. Then, poured it all over the top of the fried patties. Baked for 30 minutes. So good. We liked them this way so much better than the regular way.
