Popover Pizza Casserole

Preheat oven to 400 degrees Fahrenheit. In an oven-safe large skillet, cook turkey, mushrooms, squash, onion and sweet pepper over medium heat until meat is brown and vegetables are tender, stirring to break up meat as it cooks. Drain off fat. Stir pizza sauce, Italian seasoning and fennel seeds into meat mixture. Bring to boiling; reduce heat. Simmer, uncovered, for 5 minutes, stirring occasionally. Spread to an even layer.

Meanwhile, for popover topping: In a medium bowl, combine milk, eggs and oil. Beat with an electric mixer on medium speed or whisk for 1 minute. Add flour; beat or whisk about 1 minute more or until smooth.

Sprinkle mozzarella cheese over meat mixture in skillet. Pour popover topping evenly over mixture in skillet, covering completely. Sprinkle with Parmesan cheese.

Bake, uncovered, for 30 to 35 minutes or until topping is puffed and golden brown. (Casserole may look a bit gooey on top of the meat mixture from the melted cheese.) Serve immediately.
