I occasionally make spaghetti with meat sauce or a veal or chicken parmesan, but I feel that many Southern Italian dishes start to taste too samey what with the pasta, cheese, tomato sauce mixture maybe using different shaped pasta, but tasting very similar. I prefer Northern Italian dishes which don't rely so heavily on tomatoes. I make a dish from a recipe by Lidia Bastianich which has pasta, garlic, Italian sweet or hot sausage, leeks, mushrooms, cabbage (I sometimes leave out the cabbage), chicken broth and fontina cheese. The cheese is added into the dish at the end and it melts into the chicken broth to create a lovely sauce. I also love to make Veal Marsala, PC or not. And pesto! I'll eat anything with pesto in it or on it (except liver). I make a dish my mother used to make from some magazine recipe which she called Italian Flank Steak. I'm not sure if it is authentically Italian, but it is very good. Flank steak dredged in garlicky seasoned flour, browned in vegetable oil, then chicken broth is added to deglaze the pan and then several cloves (yes cloves, the things one pokes into ham), lemon juice and minced garlic are added (I put in sliced mushrooms too), the pot is covered and the steak simmered for 90 minutes. The meat is meltingly tender and the sauce is wonderful. This is one of my husband's favorites and it is so easy to make.
And sometimes just some cooked spaghetti with melted butter with some fresh minced garlic stirred into it and some grated fresh Parmesano Reggiano is all it takes to make me happy.
