1/4 c. water

Cook squash and onion in water, sugar, and salt until tender. Drain off liquid. Put in mixing bowl and beat until smooth. Add the remaining ingredients and pour into a greased 2 quart casserole dish. Bake at 350 degrees for 30-40 minutes. The mixture will become set and slightly browned on top.
