Preheat oven to 350°. Cook pasta according to package directions for al dente; drain.

Meanwhile, in a large skillet coated with cooking spray, cook and crumble beef with 1/2 cup mushrooms, onion and green pepper over medium-high heat until no longer pink, 5-7 minutes. Stir in seasonings and tomato sauce; bring to a boil. Reduce heat; simmer, covered, 15 minutes.

Place pasta in an 8-in. square baking dish coated with cooking spray. Top with meat sauce and remaining mushrooms. Sprinkle with 1/4 cup mozzarella cheese and 1 tablespoon Parmesan cheese.
