Cook the elbow macaroni in a stock pot until al dente, drain, and set aside. In the same pot, brown the ground beef with the onions and season with salt and pepper the way you like it. For this dish, I use more pepper than usual. Add the tomatoes and cook for about 20 minutes on medium heat. Add the macaroni last and taste again for salt and pepper, adding more if it needs it. That's it!
