10 oz. cheese; half Swiss and half Gruyere, or in proportion desired
4 tbsp. butter
2 lg. firm tomatoes (sliced)
3/4 c. cream
2 tbsp. flour
2 lg. onions
1 tbsp. chopped basil
2 lg. eggs

Prepare your favorite pastry recipe and line a 10 inch pie dish and chill it. Grate all the cheese and toss it with the flour. Melt the butter in a large skillet, slice the onions and saute them very gently in the butter until they begin to turn golden, about 1/2 hour.

Spread about 1/3 of the cheese over the bottom of the pie dish, then spread the onions over it. In the butter that is left in the pan, heat the tomato slices with the chopped basil for a minute or two.

Arrange the tomato slices over the onions, then cover with the remaining cheese. Beat the eggs with the cream and pour it over the cheese. Sprinkle top with nutmeg. Bake in a preheated 350 degree oven for 35 to 40 minutes. Serves 6.
