Cook pasta according to package directions; drain and keep warm. Meanwhile, drain about 1 T. of the olive oil from the tomatoes into a skillet. Add the onion and mushrooms; cook for about 4 minutes, or until the onion is transparent and the mushrooms are tender. Add tomatoes; cook an additional 2 minutes. Remove from heat and toss with pasta; serve with grated soy parmesan if desired.
