Put a little oil in a large skillet and brown the sausage. Make sure to get all the sausage with that nice crispy outside. Remove to a bowl when completed.
Add the red pepper and onion to the pan you cooked the sausage in. When it's nearly done (a few minutes) add the garlic and continue cooking another 1 minute.
Add the Broth to the pan and scrape any of the flavorful bits from the pan. Dump in the dried pasta and Cajun seasoning. Let cook 12-14 minutes or until pasta is done (don't overcook it). Stir it at least 1 or 2 times during cooking.
Add the cream cheese a little at a time until it's fully melted in, stirring constantly.
Dump in the sausage, giving it a thorough mixing and serve immediately for best results.
Options: Add more seasoning or red pepper flakes if you want it spicier.
Reheating: If you have leftovers, I suggest adding about a teaspoon of milk to the bowl to help make it creamy again as the noodles will absorb the juices.
