This recipe is just lacking a few ingredients and adjustment on cooking instructions. Add a few tablespoons to tomato paste and that will keep the sauce from being too watery. Second if its bland add some fresh herbs if you have them on hand or add dried ones instead. I personally added dollops of ricotta because that is what intrigued me about this recipe, but instead of adding it to the plates I transferred the pasta to a baking dish added the ricotta and sprinkled some mozzarella and baked it until the cheese was heated through. After all the adjustments I think this is a pretty solid recipe.
