I'm a big fan of dishes I can serve up with "everything" in them! Less serving dishes on the table. LOL. This sounds more involved than it is. Like a stir fry, if you prep ahead of time you can do lots of the cooking while the pasta is cooking.
Cook the fettuccine according to package directions; drain well. Set the fettuccine aside.
Cook the sausage in a large skillet over medium heat until browned on all sides; drain well, discarding the drippings. Set the sausage aside.
Saute the green onions and garlic in butter and oil in a large skillet over medium heat for 3 minutes. Add the zucchini, broccoli, and mushrooms, and saute 3 to 5 minutes. Add the reserved sausage, tomato, and the next 6 ingredients; cook 3 minutes.
Combine the cooked fettuccine and vegetable mixture; toss gently. Sprinkle with mozzarella and Romano cheese; toss well. Serve immediately.
