Choose a heavy cooking vessel with a cover (I love my cast iron dutch oven, but it doesn’t have to be). Brown the Italian sausage (I like to add a bit of oil to help it from sticking as it cooks). Remove from the pan and set aside.
Add olive oil, diced peppers and onions. Cook, stirring often, for about 7 minutes. Add garlic and cook for an additional 2-3 minutes. Stir in the remaining ingredients (except cheese and green onions) and bring to a boil.
Lower to a simmer, cover, and cook for 15 minutes, until rice is done. If you opt for brown rice (which I have done), increase the cook time to 40-45 minutes. Leave the cover on and don't check the rice. It will cook. Just be patient.
Once the rice is cooked, top with shredded cheese, remove from heat, and replace the cover until the cheese is melted. Serve with sliced green onions.
