The Cooking Process:

Heat a large skillet over medium-high heat.
Brown the Italian sausage on all sides, breaking it up with a wooden spoon. Remove and set aside, leaving the fat in the skillet.
Cook the ground beef in the same skillet; set aside after cooking.
Sauté the onion in the skillet until slightly browned, about 5 minutes.
In a slow cooker, combine the cooked sausage, beef, onion, and the remaining ingredients. Cover and cook on high for 6 hours.
Before serving, remove the Parmesan cheese rind.
This soup delivers a delightful makeover to the Italian-American stuffed pepper, with a harmonious blend of Italian sausage, basil, oregano, garlic, and a kick of red pepper flakes. The addition of a Parmesan rind infuses the soup with a rich umami flavor. Enjoy this hearty, comforting dish that simplifies a classic while keeping all its beloved flavors.”
