There is a good idea for a quickly prepared impromptu lunch. Pretty much your regular “quiche lorraine” recipe with added spinach. We had that today with a fresh beet salad on the side. It was a perfect winter lunch.
For one pie crust, I cooked 4 slices of bacon cut in small bits in a frying pan with four sliced white mushrooms and a quarter of a chopped large onion for about 5 minutes. This I mixed with 5 eggs beaten with 1/4 cup cream (or homo milk). I added one package of frozen spinach ( about the equivalent of a fresh bunch) salt and pepper. Mix well, pour into the pie shell, add small slices of cheese on top, raclette cheese today. Bake at 350 for 40 minutes. Turn off and serve 5 minutes later. I served it with sliced beets sprinkled with balsamic vinegar and truffle oil.
