A quick, simple recipe that Jim acquired from an unknown source during his bachelor days. He always says it's even better the next day.
In Dutch oven or large deep skillet, brown first 4 ingredients in olive oil. Sprinkle with salt, stir in water. Bring mixture to a boil; add spaghetti, cook uncovered, 12-15 minutes or until spaghetti is tender. Stir in tomatoes, tomato sauce, and mushrooms; simmer about 10 minutes to blend flavors. Serve with Parmesan cheese if desired. Makes 6-8 servings (about 8 cups).
