Directions Combine flour and salt; cut in butter until crumbly. Gradually add 3-5 tablespoons ice water, tossing with a fork until dough holds together when pressed. Wrap in plastic wrap and refrigerate 1 hour. Preheat oven to 450degrees. On a lightly floured surface, roll dough to a 1/8-in.-thick circle; transfer to a 9-in. pie plate. Trim pastry to 1/2 in. beyond rim of plate; flute edge. Line unpricked pastry shell with a double thickness of heavy-duty foil. Bake 5 minutes; remove foil. Bake 5 minutes longer; remove from oven and cool on a wire rack. Reduce heat to 375degrees. Sprinkle bacon, cheeses and onion over crust. Beat remaining ingredients until blended; pour over top. Bake until a knife inserted in center comes out clean, 30-35 minutes. Let stand 10 minutes before cutting. Yield: 6 servings.
