My husband and I value our time with our friends and try to spend 2 nights a months with them. However, after a night of dancing, singing and "merriment" I am too wiped out the next morning to make breakfast. I solved that problem by making this quiche the day ahead, then cooling and storing in the fridge. It is awesome reheated the next morning. Add some fruit and yogurt and you have a great meal.
1Preheat oven to 350 degrees (F). Line a 9" pie plate with crust, following package directions for a one crust pie.
2Toss shredded cheese with flour. Beat eggs, half and half (or milk), salt and pepper in a large bowl until well blended. Stir in sausage, cheese and onions, if desired. Pour mixture into crust.
3Bake 40 to 45 minutes or until the edges are golden brown and a knife inserted near the center comes out clean. Let stand 5 minutes before serving. Or cool completely and cover and refrigerate until the next day.
Cover the edge of the crust with foil if it browns too quickly.
When reheating, cut into slices and reheat one at a time in the microwave.
