2 c. all-purpose flour
1/2 tsp. salt
1/2 c. butter
4 tbsp. ice water (about)

FILLING:

1 1/2 tbsp. butter
6 lg. onions, thinly sliced
1/2 tsp. salt
1/3 c. diced bacon
2 c. milk
3 tbsp. all-purpose flour
2 eggs, well beaten
2 c. shredded cheese

To make dough: Sift flour with salt. Cut in butter until particles are the size of small peas. Add ice water. Stir until a stiff dough is formed. Knead on a lightly floured board. Roll out to fit the bottom and sides of a well buttered 10 inch layer cake pan. Prick dough several times with a fork.

To make filling: Heat butter in a pan and saute onions. Add salt and diced bacon. Cook over medium heat until onions and bacon are golden brown. Add milk gradually to the flour. Stir until smooth. Beat in eggs and cheese. Add sauteed onions and bacon, including the fat in which they were sauteed.

Pour mixture into dough-lined pan. Bake at 350 degrees for 30 minutes. Raise oven temperature to 400 degrees and bake 5 minutes longer, or until top is browned and crisp. Cut into wedges; serve hot. Serves 6.
