In 12-inch skillet, heat 1 tablespoon extra-virgin olive oil or vegetable oil over medium-high heat until hot. Cook mushrooms in oil 4 to 6 minutes, stirring occasionally, until lightly browned and tender.
Add cooking sauce, vegetables, Italian seasoning, 1/4 teaspoon salt and 1/8 teaspoon pepper; heat to boiling. Reduce heat; simmer uncovered about 15 minutes or until thickened. Serve mushroom mixture over fettuccine; sprinkle with cheese.
