1 can (4 ounces) mushroom stems and pieces, drained
2 cups shredded cheddar cheese, divided
1/3 cup chopped onion
2 cups biscuit/baking mix
1/2 cup water
4 large eggs
1/2 cup whole milk
1/4 cup grated Parmesan cheese
1/2 teaspoon salt
1/2 teaspoon pepper
In a small saucepan bring 1 in. of water to a boil. Add broccoli; cover and boil for 3-5 minutes or until crisp-tender; drain and set aside.
In a large skillet, cook beef over medium heat until no longer pink; drain. Stir in mushrooms, 1-1/2 cups cheddar cheese and onion. Remove from the heat and set aside.
Combine the biscuit mix and water to form a soft dough. Add remaining cheddar cheese; stir until blended. With well-floured hands, pat dough onto the bottom and 1 in. up the sides of a greased 13x9-in. baking dish.
Spoon meat mixture over dough; top with broccoli. Combine the eggs, milk, Parmesan cheese, salt and pepper; pour over broccoli. Bake, uncovered, at 350° for 35 minutes or until a knife inserted in the center comes out clean.
