How to make
Heat the oven to 430°F (220 °C). In a large pot, boil water and put the lasagna sheets in it for 5 min. Then wash the lasagna sheets with cold water and sprinkle with a little oil, to prevent sticking. Chop the onion and sauté it in a large skillet with olive oil. Grate the zucchini and garlic and 3 minutes later, add them to the onions in the skillet.
Once the Zucchini soften, add 2/3 of the cheese, stir and flavour them. Heat up the tomato sauce in the microwave.
In a large oven dish, start to stack the lasagna. Start with the zucchini, sheet of lasagna and tomato sauce. Top with cream cheese and grated cheese. Bake 10 minutes in the upper part of the oven until the cheese turns golden.
