Cooking the dried pasta in the same vessel as the sauce not only makes for fewer dishes to clean, but the dish will be creamier. The pasta is cooked by absorption of the liquid. Use just enough to tenderize the noodles, leaving a small amount of starchy stock in the pan. Those wheat starches thicken the sauce because it's not being diluted in a large pot of water like traditional boiling methods. The pasta is also better seasoned because it's simmered with the cajun spice blend.
