This recipe worked out really well after some revisions based on others' suggestions. Here's what I did: 1/2 box of small shell pasta, 12 oz. can tuna, 16 oz. fresh mushrooms (sliced), 2 cans cream of mushroom (10.75 oz.), 1 3/4 cans of milk, 1/2 cup bread crumbs, 3 tbsp. butter, seasonings to taste, Other than that, I cooked in the oven for 60 min. All other actions were based on the recipe's suggestion. Will definitely make again.



This is so easy! It is also a recipe that converts to low fat! Use the 99% fat free cream of mushroom, semi skimmed milk, a smaller amount of butter and low fat saltine crackers for the topping. My husband couldn't tell the difference.



I can only give this recipe a three stars. There were so many bread crumbs called for that it dried out the casserole. My husband and I ended up scraping off the crumbs and eating the casserole. I will make this again but will sprinkle cheese on the top as a topping and I will use peas inside the casserole with the mushrooms.
