Pasta E Fagioli Soup

This soup was pretty tasty. It's supposedly a copy-cat recipe from the Olive Garden. It tasted like a beefy minestrone to me. I got it from Recipezaar, but have modified it a little.

Ingredients:
1 lb ground beef
1 small onion, chopped
3 carrots, chopped
3 stalks celery, chopped
2 (28 ounce) cans diced tomatoes, undrained
1 (16 ounce) can red kidney beans, drained
2 (10 ounce) cans beef stock
1 can water
3 teaspoons oregano
2 teaspoons pepper
5 teaspoons parsley
1 teaspoon Tabasco sauce (optional)
1 (20 ounce) jar spaghetti sauce
8 ounces pasta
Parmesan cheese

Directions:
1. Brown beef in skillet, drain grease.
2. Add beef and all remaining ingredients, except pasta and spaghetti sauce, to large sauce pan. Cook over medium high heat until vegetables are tender. About 15 min.
3. Add spaghetti sauce, bring back to a boil.
4. Add pasta, cook according to package
5. Serve topped with parmesan cheese.
