How to make
Cut the meat into 4 or 6 large portions.
In a bowl, mix the spices, mix very well and spread the portions of meat with them.
Cut the onion and mushrooms and pour them into a baking pan, place the flavored meat and the rest of the spices mix with a little water and pour them over the mushrooms.
Drizzle with a little oil and roast in a moderatey heated oven.
If you want the roasted pork to have an appetizing crust, you can leave some of the spice mixture and smear them with the glaze several times during roasting.
