This is easy comfort food. All you need is a green salad. I have used cheddar and Swiss cheese in this. I am having to guess at the measurements. Edited to add that after posting this recipe, I decided to make it for an easy supper before the fire. Of course I could not find the shrimp and crab in the freezer so I substituted smoked salmon. Wow! it was good. I made 2 cups white sauce, used colby/jack cheese, fresh dill and was out of mushrooms. My husband wanted to know when we could have it again.
