Cut the green peppers into strips and the onion into slivers.
Heat a Dutch oven over medium-high heat. Add the sausage, peppers, and onions, and cook until the sausage is browned, breaking it into crumbles as it cooks.
Add the tomatoes and chicken broth, turn the heat down to medium, and simmer for 10 minutes, until the peppers and onions are soft.
Add the cream cheese cubes and whisk until they melt into the liquid. Pour in the heavy cream, then add the parmesan cheese, one ounce at a time, stirring until it's melted before adding the next batch.
Taste for seasoning, add salt and pepper if needed, then remove from the heat and serve.
