Olive Garden's Pasta E Fagioli

I found the original recipe on crockpot 365 and it is also on my friend Maleah's blog. I don't use a full lb of beef and I decided I liked it better with italian seasoning rather than all oregano. You can use any combination of veggies that you want. You could add broccoli, squash, green beans, asparagus, corn, etc.. We all love this soup at our house!
Ingredients:
1/2 lbs ground beef, cooked and drained
1/2 onion, chopped
1 cup carrots, chopped
1 cup celery, diced
2-14 ounce cans diced tomatoes
1 can red kidney beans, drained and rinsed
1 can white kidney beans, drained and rinsed
4 cups(32 oz) beef stock
1-2 teaspoons italian seasoning
salt and pepper
3-4 cups spaghetti sauce
1/2 dry pasta shell macaroni(added during the last hour of cooking)

Add all ingredients except pasta to crockpot. Cook on low 8 hours and add the pasta during the last hour.

Time saving tip: I usually assemble this in my crockpot the night before I plan on cooking it. I keep it in the fridge overnight and just have to plug in my crockpot in the morning. If I end up having a hectic morning I'm so glad I took the extra time the night before.
