Beefy Spaghetti

Bring a large pot of salted water to a boil. Meanwhile, in large skillet, cook ground beef with onion and garlic until beef is browned, breaking up beef with a fork so it cooks evenly. Drain well if necessary. Add pasta sauce to ground beef mixture. Add 2 tablespoons water to pasta sauce jar, close lid, and shake to loosen remaining sauce. Pour into ground beef mixture. Bring to a simmer, then reduce heat and simmer, stirring frequently, while the pasta cooks. Cook spaghetti according to package directions until al dente. Drain well and place on serving plate. Top with meat sauce, sprinkle with cheese, and serve immediately.
