1 med. onion, sliced thin
1 can Cream of Chicken soup (any cream soup will work)
1 pint sour cream
4 2/3 C. Pepperidge Farm stuffing mix (anything besides Stove Top will work)
2 sticks butter
shredded cheddar cheese (swiss is yummy too) optional
Melt 1 stick of butter and mix with 2 1/3 C. of the stuffing mix. Press into the bottom of the casserole dish. Par boil sqaush and onions until just lightly tender. Mix Cream Soup with Sour Cream, Summer Squash and Onion. Pour mixture on top of stuffing mix. I top with some shredded cheese. Melt 2nd stick of butter and mix with remaining stuffing mix. Top casserole with stuffing mix. I usually put this in the fridge for a few hours to allow everything to really come together. Then I bake it covered with foil for 30 minutes on 375. Then I uncover it and bake for an additional 10 - 15 minutes.
