First, put the springform pan on a peice of foil and run the foil up the sides (in case there is spillage). Spread HALF the onion mixture on the bottom of the pie crust, and sprinkle with HALF of the bacon. Sprinkle 3/4 cup of the cheese over the bacon and onions. CAREFULLY and SLOWLY pour HALF the egg mixture in. Repeat with the other half of the oinions, bacon and egg mixture...not the cheese.
