Add salt, pepper, oregano, tomato sauce, diced tomatoes, and mushrooms to beef. Simmer sauce for 20 to 30 minutes. While sauce simmers, cook spaghetti in a large pot according to package directions. Place half of the cooked spaghetti in prepared baking dish. Spread half of the meat sauce over the spaghetti.
