Boil the lasagna noodles according to instructions behind the package.

Meanwhile fry the minced pork together with chopped onion in a pan. Make sure they are both cooked.

Add creme fraiche and around 1/3 of the pasta/lasagna sauce into the pork with onion. Season with garlic powder, salt and pepper.

Finely chop the spinach. Mix with 3 cups of parmesan cheese and the egg. Pour in the remaining pasta/lasagna sauce and mix well.

Preheat oven to 250°. Spray the baking tray with cooking spray and spread a bit lasagna/pasta sauce on its surface.

Drain the cooked lasagna sheets and put 2 pieces side by side in the baking tray. Spread the pork and onion sauce, following by spinach cheese sauce. Then repeat the process until you run out of lasagna sheets.

Sprinkle as much cheese and spinach as possible on the top surface of lasagna. Bake in oven for around 20 minutes and voila!
