Preheat oven to 450 degrees F. In a large bowl combine egg, 1/2 cup of the pasta sauce, the bread crumbs, 2 tablespoons of the basil, and the salt. Add ground beef and 1/2 cup of the cheese; mix well.
Divide meat mixture into four portions. Shape each portion into a 5-1/2x2-inch oval loaf. Place in a 15x10x1-inch baking pan. Top loaves with the remaining 1/2 cup pasta sauce and the remaining 1/2 cup cheese. Bake about 15 minutes or until an instant-read thermometer registers 160 degrees F.
Meanwhile, in a medium saucepan cook green beans in a small amount of boiling salted water for 10 minutes; drain. Return beans to hot saucepan. Add oil and, if desired, crushed red pepper; toss gently to coat. Serve meat loaves with green beans. Sprinkle with the remaining basil.
