Today, you want to prepare delicious Cannelloni pasta. This is a much-loved dish originating from Italy, famous for its greasy taste and absorbing sauce. This special dish is prepared at afternoon lunches, ensuring nutrition and, of course, filling your stomach. To get started, make the bechamel sauce first in a medium-heated skillet. Melt the butter and flour and stir in the pan for about 2 minutes. Next, add milk and salt and cook until the sauce thickens. Then prepare the Cannelloni filling in a heated frying pan by adding olive oil, minced onion, and ground veal. Next, transfer the filling to a large bowl and add the ground mortadella, minced prosciutto, steamed spinach, ricotta cheese, parmesan cheese, salt, pepper, and oregano. Mix well. Finally, complete the dish by putting them in the oven, adding tomato sauce, and spreading grated parmesan cheese on top. I hope you have fun!
