In a Dutch oven or soup pot, over med heat, start browning Italian sausage; chopping it up as you go like you would ground beef.
Once it starts browning throw, in onion and garlic and let it start to sweat for about 2 minutes; don’t let it brown.
Next, add the carrots; keep tossing it around until the onions are opaque and the sausage is cooked through.
Pour in the chicken broth, water, Rotel tomatoes, Italian seasoning, salt, pepper, garlic powder and tomato paste.
Let it simmer together for 30 minutes.
Taste and add more salt if you wish, but keep in mind you are going to add Parmesan cheese which is salty as well.
After simmering for 30 minutes, add the frozen tortellini and simmer for another 10 minutes or until the tortellini is cooked through.
Serve this Italian Tortellini Soup hot and top with Parmesan cheese.
You can try it without but I promise you the Parmesan makes this dish.
