Remove the casing from the Italian sausage, and fry in a large soup pot over medium-high heat, Break up the sausage as it cooks into bite-sized pieces.

Once the sausage is browned, add in the chopped onion and garlic, and cook until the onion is transparent.

Add in the chopped carrots (I do rounds, cut in half again), the chicken stock, diced tomatoes, water, Italian seasoning, garlic powder, salt and pepper. Bring to a boil, and simmer with a lid for about 20 min.

Add in the chopped zucchini (again cut in rounds, and half again), and simmer for another 10 min.
Lastly, add in your tortellini and frozen corn and cook according to the package directions -fresh is about 10 min., frozen is longer. Once the tortilla is tender the soup is ready to enjoy.
