Broccoli Biscuit Squares Recipe

In a large skillet, cook the beef, mushrooms and onion over medium heat until meat is no longer pink; drain. In a large bowl, combine biscuit mix, 1/2 cup cheddar cheese, Parmesan cheese and water until a soft dough forms. Press dough onto the bottom and 1/2 in. up the sides of a greased 13x9-in. baking dish. Stir remaining cheddar cheese into the beef mixture; spread over dough. Sprinkle with broccoli. In a large bowl, beat eggs, milk, salt and pepper. Pour over meat mixture. Bake, uncovered, at 400 ° for 25 minutes or until a knife inserted near the center comes out clean.
