Preheat oven to 350°. In a large bowl, combine eggs, egg yolks, whipping cream, half-and-half, mozzarella cheese, 1/2 cup cheddar cheese, Swiss cheese, tomatoes, seasoning blend and basil; pour into a greased 9-in. deep- dish pie plate. Sprinkle with remaining 1/4 cup cheddar cheese.
Bake 45-50 minutes or until a knife inserted in the center comes out clean. Let stand 10 minutes before cutting.
