In a large stockpot, brown both the hot and mild sausage.
Pour off any excess liquid.
Add a small amount of chicken broth to deglaze the pan to loosen any small bits of sausage.
Add the remaining chicken broth, the canned tomatoes (with juices).
Mix in the dry soup mix, Italian seasoning, black pepper, red pepper flakes, and cheese rinds.
Drain and rinse the canned beans under cool water and add them to the soup pot.
Dice some fresh basil and add it to the soup pot.
Bring it to a boil and reduce it to a simmer, uncovered for 50-60 minutes.
Remove the cheese rinds, taste, and add salt if needed.
Garnish with fresh basil and serve with toasted garlic bread.
