In a medium sauce pot over medium heat, saute garlic in extra-virgin olive oil. Chop whole tomatoes and add them to the pan. Add crushed tomatoes and salt and simmer 10 minutes, add basil and simmer over low heat 10 minutes more.
Add salt and pasta to boiling water and cook 6 minutes, leaving pasta a little chewy.
While pasta cooks, melt butter in a small pot over medium heat. Whisk in flour, then cook 1 minute, adding salt and pepper and nutmeg to flour. Add milk and bring sauce to a bubble. Reduce 5 minutes.
Drain pasta and transfer to a large flameproof casserole dish. Pour the tomato and basil sauce over the pasta and turn to coat the pasta. Pour the bechamel over the already coated pasta. Cover the top of the pasta with Asiago, Parmesan and mozzarella. Place the casserole under hot broiler and melt the 3 cheeses until brown and bubbly, 3 to 5 minutes. Serve immediately with Spinach and Artichoke Salad and bread.
