1/2 cup finely chopped fresh basil leaves
salt and freshly ground black pepper, to taste (I didn’t add any salt because the sausage, tomatoes broth and cheese were salty enough )
Add the onions and garlic to the pot and cook until the onions have softened, about five minutes.
Stir in the dried oregano, crushed red pepper and the tomato paste. Cook the tomato paste until it has browned slightly and evenly coated the meat and onions, 3-4 minutes.
Add in the diced tomatoes, bay leaves and chicken broth, then turn down the heat to medium-low and simmer 30 minutes.
Crank the heat back up to medium-high and bring to a boil before adding the pasta. Cook until al dente according to the package directions (probably 8-10 minutes).
While the pasta is cooking, mix the ricotta, parmesan and pepper together in a little bowl.
Once the pasta is al dente, spoon a little of the ricotta mixture in each serving bowl, then ladle the soup over. Sprinkle with chopped basil and the shredded mozzarella.
