1-1/2 pound zucchini
3 medium-sized ripe tomatoes
4 tablespoons butter, divided
1 tablespoon vegetable oil
3 eggs, separated
2 cups Swiss cheese, grated, divided
1/2 cup feta cheese, divided
1 teaspoon dried Italian herbs, divided
1 baked pie shell
Wash the zucchini, then peel and thinly slice or julienne it. Lightly salt it, place in a colander and let stand in the sink for 30 minutes. Lightly squeeze the zucchini to remove more water.
Preheat the oven to 375 degrees Fahrenheit.
Peel the tomatoes, slice, and remove the seeds.
In a large saute pan, heat 2 tablespoons of the butter with the 1 tablespoon of vegetable oil. Lightly brown the zucchini or both side, the drain.
Lightly brown the tomatoes until they soften slightly but do not become limp.
Beat the egg yolks and set aside.
Place half the zucchini in the baked pie shell. Sprinkle with 2/3 cup of grated Swiss cheese and 1/4 cup of feta cheese, dot with 1 tablespoon of butter, and sprinkle with 1/2 teaspoon dried Italian herbs.
Beat the egg whites and fold into the yolks. Spread half of this mixture over the cheeses.
Arrange the tomatoes slices across the pie. Sprinkle with 2/3 cup of grated Swiss cheese and the remaining feta cheese and dried Italian herbs.
Top with the remaining half of zucchini. Spread remaining half of egg mixture over top, sprinkle the remaining 2/3 cup of Swiss cheese, and dot with the remaining 1 tablespoon of butter.
Bake at 400 degrees Fahrenheit for 15 minutes, then at 375 for another 20-30 minutes or until the eggs are set.
