Here's a piece of pork on the bone I had was already sliced into patties at the market. If You have a solid piece of meat, make the cuts yourself.

Finely chop the onion and fry until transparent in vegetable oil, add the spinach. It can be pre-thawed, and you can put frozen, like I did. If You have fresh spinach, then, in General, wonderful work. Wait until spinach is completely thawed in the pan...

... and add finely chopped peeled Apple. Apple is better to take a hard, sour. Season with salt and pepper, add the nutmeg. Put out a couple of minutes, remove from heat. Be sure to try the stuffing! At this stage there is still time to needs more salt and doperchit. You can slightly overdo it with the salt - the meat will absorb the excess. Not long keep the stuffing in the pan! Need one or two minutes - only slightly damp.

In the meantime, to beat the meat patties through the foil to avoid splashing. Season with salt and pepper.

On each chop put the filling, a slice of cheese and again to cover the filling. To do with all the meat slices.

Meat tightly tie a thread to keep the form and put in sleeve or wrap in foil. Put in the hot oven. I baked it for an hour and a half at 200 degrees.

After baking to let the meat cool slightly, remove the thread and help yourself!
