In a large bowl, combine the flour and baking powder. Add the eggs, 3-1/2 cups Monterey Jack cheese, cottage cheese, tomatoes, chilies, onions, hot pepper sauce, oregano, optional cilantro, salt and pepper. Pour into a greased 13-in. x 9-in. baking dish. Sprinkle with the remaining Monterey Jack cheese.
Bake, uncovered, at 400° for 15 minutes. Reduce heat to 350°; bake 30 minutes longer or until a knife inserted near the center comes out clean. Let stand for 5 minutes before cutting. Serve with salsa, if desired. Yield: 8 servings.
