Tortiglioni with Zucchini - An Italian Classic

1 Clean the zucchini well, peel them and slice them in thin slices. In a frying pan add the butter and the olive oil. When the butter is melted add the onion.
2 As soon as the onion is beginning to soften, add the zucchini to the skillet and with high heat for a couple of minutes. Lower the heat to medium-low and cook slowly. Add salt, pepper and keep warm.
3 Meanwhile cook the pasta according to the package directions. While the pasta is cooking, in a large bowl beat the two eggs, slightly salted them and add plenty of Parmesan Cheese.
4 When the pasta is al dente, drain and add to the egg mixture. Mix well and add the zucchini. Mix well again and serve immediately.
