Here are the recipes I plan to use, both culled from AllRecipes.com, one of my favorite idea spots.
Preheat oven to 425 degrees F (220 degrees C).
Place bacon in a large skillet, and fry over medium-high heat until crisp. Drain on paper towels, then chop coarsely. Sprinkle bacon, cheese and onion into pastry shell.
In a medium bowl, whisk together eggs, cream, salt, sugar and cayenne pepper. Pour mixture into pastry shell.
Bake 15 minutes in the preheated oven. Reduce heat to 300 degrees F (150 degrees C), and bake an additional 30 minutes, or until a knife inserted 1 inch from edge comes out clean. Allow quiche to sit 10 minutes before cutting into wedges.
Preheat oven to 350 degrees F (175 degrees C).
Beat together flour, salt, half-and-half and eggs in a medium bowl.
Place Swiss cheese flat in the pie crust. Arrange spinach evenly over Swiss cheese, then cover with mushrooms. Pour the flour and egg mixture over mushrooms. Cover with flaked ham and top with Cheddar cheese.
Bake in the preheated oven 45 to 55 minutes, until surface is golden brown.
