Heat the oil on medium heat in a large, deep skillet with a tight fitting lid. Add the onion, peppers and sausage and cook until the veggies are softened and sausage is beginning to brown. Stir in the garlic and cook another couple of minutes, until fragrant. Then increase the heat to med-high and stir in the diced tomatoes, broth, cream, seasonings and the pasta.
Once it begins to boil, reduce heat to medium-low and place lid on. Simmer about 11-13 minutes, stirring occasionally, or until pasta is al dente and the majority of the liquid has absorbed.
Remove from heat and stir half of the cheese into the pasta until its melted. Let it sit for a couple of minutes, to let the sauce thicken, then sprinkle the remaining cheese over the top of the pasta. Place lid back on until cheese is melted, about 2 minutes. Serve immediately and enjoy!
