Preheat oven to 190ºC (375ºF). In a casserole filled with boiling salted water, cook noodles al dente. Drain.
Meanwhile, heat oil in another casserole over medium heat. Brown meat for 2 to 3 minutes. Add leeks, spinach, and seasoning. Cook for 3 to 4 minutes.
Lay the preparation on a rectangular plate 33 cm x 23 cm (13 inches x 9 inches). Cover with ricotta. In the same casserole you cooked noodles in, mix the noodles with tomato sauce and parsley. Heat for 2 to 3 minutes at medium heat, then divide equally on the plate. Lightly press the surface and cover it with mozzarella.
Cover with aluminum paper and oven-bake for 15 minutes. Remove aluminum paper and continue cooking for 10 minutes.
