Lightly grease a 9-inch pie plate. Pour egg mixture into pie plate. Bake, uncovered, in a 375 degree F oven for 25 to 30 minutes or until golden brown and a knife inserted near the center comes out clean.
Meanwhile, in a small saucepan heat the spaghetti sauce over medium-low heat about 5 minutes or until warm, stirring occasionally.
To serve, cut egg mixture into wedges. Top with spaghetti sauce. If desired, garnish with basil. Makes 6 servings.
