Put the pot over medium-high heat and cook
the pancetta 4 to 5 minutes. Addd the onions,
season generously with salt and stir to coat with
the olive oil. Cook 6 to 7 minutes, the
onions should become very soft and aromatic
but have no color. Add the garlic and cook for
another 2 to 3 minutes, stirring frequently .

2- Pass the tomatoes through a food mill; be
sure to scrape the pulp off the bottom of the food
mill. Add the tomatoes to the pot; fill one of the
empty tomato cans with water and add to the pot
(2 to 3 cups). Season generously with salt and taste;
tomatoes take a lot of salt. Simmer 2 to 3 hours over
medium-low heat, stirring occasionally and tasting
frequently. Season in baby steps, tasting every step
of the way.

3- Make the lasagna: Bring a large pot of salted
water to boil. Working in batches, cook the lasagna
noodles until pliable but not limp, 6 to 7 minutes.
Remove with tongs and transfer to a bowl of ice
water to cool; remove and lay flat on a sheet tray.

4- Coat a large saute pan with 2 tablespoon olive
oil and put over medium-high heat, Add the sausage
and cook, stirring until brown and crumbly. Remove
from the pan and drain on paper towels.

5- Ditch the fat from the pan and add 1 tablespoons
olive oil along with 2 garlic cloves and a pinch of red
pepper flakes. Put the pan over medium-high heat.
When the garlic is golden, remove it and discard.Add
the mushrooms and season with ½ teaspoon salt;cook
until soft, 4 to 5 minutes.Remove from the pan and
reserve. Repeat this process with the remaining
1 tablespoon olive oil,2 garlic cloves and pinch of red
pepper flakes, and the zucchini.

6- In a bowl, mix the ricotta, half of the parmigiano,
the eggs, basil and 1 teaspoon salt.

7- Preheat the oven to 350°, In the bottom of a deep
9-by-13-inch baking dish, evenly spread a couple ladlefuls 
of  sauce. Cover with a layer of the lasagna noodles. Spread 
one-third of the ricotta mixture over the pasta. Top with a 
layer of pasta in the opposite direction of the first layer 
(this will give the lasagna a little more stability). Spread a 
light layer of sauce on the pasta and sprinkle with one-third
of the sausage.top with  one-third of the mushrooms and 
zucchini. top with a layer of mozzarella and some of the 
remaining parmigiano. Repeat these layers until all the ingredients 
have been used. Be sure to finish with a layer of pasta covered with
sauce, mozzarella and parmigiano. Cover with aluminium foil.

8- Place the lasagna on a sheet and bake in the oven 
until hot and bubbly, about 1 hour, 15 minutes, removing the foil
for the last 15 minutes of cooking. Let cool 20 minutes before slicing.
