Pasta Primavera

Prepare pasta according to package directions.  Drain and set aside.

Meanwhile, heat olive oil in a large skillet over medium heat.  Add asparagus, broccoli, mushrooms, tomatoes and half the green onions to skillet.  Stir to combine.  

Saute for 1 minute.  Cover and allow to steam for 5 to 8 minutes or until broccoli and asparagus reach desired tenderness.

Serve vegetables over cooked pasta.  Sprinkle with remaining onions and season to taste with salt and pepper.  Serve with Parmesan cheese, if desired.
