Sprinkle bacon, onion and cheese in the bottom of an unbaked pie shell.
Beat eggs slightly. Beat in remaining ingredients, then pour into the pie shell.
Bake at 425° for 15 minutes. Then reduce the heat to 300° and bake an additional 30 minutes or until a knife inserted 1" from the edge comes out clean.
Let stand for 10 minutes before cutting into wedges.
Notes
Tip from the cookbook: "To cut down on time, cook enough extra bacon while getting breakfast, for this main dish."
