In a large skillet, brown the ground beef over medium heat and drain excess fat. Add onion, green pepper, garlic, oregano, salt, water, marinara and hot sauce. Simmer for about 10 minutes, stirring occasionally, until vegetables are tender and sauce is slightly thickened. In a medium bowl, whisk together milk, oil, and eggs for 1 minute. Gradually add flour and salt, beating for 2 minutes until smooth. Pour the hot meat mixture into a 13” x 9” baking pan. Top evenly with the sliced cheese. Pour the batter over the cheese, covering the filling completely. Sprinkle with grated Parmesan. Bake at 400°F for 30 minutes, or until the batter is puffed and golden brown.
