Lentil and Ricotta Cannelloni is a delicious and hearty vegetarian dish. The cannelloni tubes are filled with a mixture of cooked lentils, creamy ricotta cheese, and flavorful herbs and spices. The dish is then baked in a rich tomato sauce until the pasta is tender and the filling is bubbly and golden. This dish is a great option for a comforting weeknight dinner or a special occasion meal. Serve it with a side salad and crusty bread for a complete and satisfying meal.
