Crockpot Pasta Fagioli Soup (tastes like Olive Garden's)

2 lbs. ground chuck, browned, drained, and rinsed, (can also be put in the crockpot raw to cook)
1 onion, chopped
3 carrots, chopped
4 stalks celery, chopped
2, 28 oz. cans diced tomatoes, undrained (I used Del Monte with basil, oregano, and garlic added)
16 oz. can dark red kidney beans, drained and rinsed
16 oz. can white kidney beans, drained and rinsed

1 can Italian green beans, optional, some recipes use them, up to you
3 cans beef broth (1 can of beef broth is 14.5 oz.), can also use beef broth in the box (comes in 32 oz)
4 T. Italian seasoning
24 oz. can spaghetti sauce (I used Del Monte with green pepper and mushrooms added)
8 oz. dry pasta

Place liner in crockpot, Place everything, except pasta in crockpot. Cook on low 7-8 hours, or high 4-5 hours. Add pasta during last 30 minutes. Serve in bread bowl if desired. Delicious!
