In a large pan, cook sausage over medium heat until cooked through, breaking it up as it cooks. Drain fat, if desired.

Add diced tomatoes and any optional seasonings to taste. Bring to a boil, reduce heat, and simmer for 10-15 minutes.

Meanwhile, cook pasta as directed on the packaging, strain, and set aside. Reserve 1 cup of pasta water for the sauce.

Turn off the heat and add pasta water and cheese, stirring until melted. Add cooked pasta and stir to coat. Serve and enjoy!
