I got this recipe from my mother-in-law. I am listing it here as she gave it to me, but I make the following changes: recipe #54128 in place of the mushroom soup (or I have also used cream cheese, maybe fat-free?) lots more garlic and onions, fresh mushrooms instead of canned, cheddar cheese spread (ie Wispride)instead of Velveeta and I skip the olives since it is one of the few foods I actually dislike. It's really a pretty tasty casserole, easy to make ahead for a crowd and it freezes well. I like to add Tabasco for a little more zip.
