Mix chicken minced meat with thyme, salt and pepper.
Onions, shallots and garlic fry in olive oil until Golden brown.
Add the minced meat and fry for 5 minutes on medium heat.
If you have fresh spinach, chop it and add to the minced meat. If you take a canned (as I did), it is necessary to strain the liquid well before it is added to the minced meat. Put out another 10 minutes.
Then remove from heat and add ricotta. Stir well.
While preparing the stuffing, boil and cool the sheets of lasagna.
Minced a little cool, put a few tablespoons of minced meat on a sheet of lasagna.
Roll into a tube. Repeat this step until you run out of lasagna sheets and minced meat.
Put the tubes in a dish oiled with olive oil. I got two dishes of 9 cannelloni.
