Spinach Pie with Mushrooms and Swiss Cheese

Mix 1 1/5 c. of each of the following in a bowl: cottage cheese, grated swiss cheese, cooked chopped spinach, sauteed mushrooms, and browned onions. Add 3 eggs, beaten, a splash of milk, and salt to taste. Pour into an unbaked pie crust (whole wheat is good) and bake at 350° for 50 minutes. Cool before eating.
