In a large saucepan, brown the ground chuck with the chopped onion. Drain and return to saucepan.
To the ground chuck, add water, diced tomatoes, diced carrots, diced celery, diced peppers, and the Italian seasonings. Simmer for 5-10 minutes, and then add the pasta.
Cook for another 10-15 minutes and reduce heat to low until its time to serve. (Don't let the soup "sit" too long on the stove, as the pasta will overcook and get mushy!)
Slice and warm bread and serve with butter and jam.
Serve Beefy Mac Soup with veggies and slices of French bread.
