Heat oil in a skillet over medium-high heat.
Add ground meats, salt, and pepper.
Saute meat until browned, about 10 minutes.
Using a slotted spoon, remove the meat from the pan and set aside.
Bring a large pot of salted water to a boil. Add the lasagna noodles and cook until al dente, about 10 to 12 minutes.
Drain and lay noodles on paper towels and pat dry.
Combine the ricotta, 1 cup of grated cheese, eggs, salt and pepper, and 1 tablespoon of parsley in a large mixing bowl. Set aside. Preheat oven to 375°F.
Arrange a slightly overlapping layer of lasagna noodles to cover the bottom of the dish.
Dot the lasagna noodles with large spoonfuls of the ricotta mixture and ground meats, spread.
Add some shredded mozzarella, and parmesan cheese.
Layer the second row of lasagna noodles, more sauce, ricotta cheese, ground meats, mozzarella cheese and a sprinkle of parmesan.
Repeat with one more layer of noodles, sauce, mozzarella cheese, and parmesan cheese.
Cover the dish with aluminum foil and bake until tile cheese is melted and the bubbly, about 45 minutes.
Remove the foil and bake until tile top layer is lightly browned, about 10 to 15 minutes.
Let stand for 15 minutes before serving.
