Fat-free half-and-half and refrigerated egg product make this egg dish lower in calories and fat than many other quiche recipes.
Prepare Baked Oil Pastry. Reduce oven temperature to 350 degrees F. Shred Gruyere cheese; you should have 3/4 cup. Set aside 2 tablespoons of the cheese.
In a large bowl, beat together remaining cheese, the egg, spinach, half-and-half, thyme, and pepper. Pour egg mixture into Baked Oil Pastry.
Bake for 40 minutes. Sprinkle with the reserved 2 tablespoons cheese. If necessary to prevent overbrowing, cover edge of quiche with foil. Bake about 10 minutes more or until a knife inserted near center comes out clean. Let stand on a wire rack for 10 minutes before serving. Makes 10 servings.
