Cut the meat into medium pieces, wrap in cling film and beat well with a hammer. Then remove the pepper and salt film and beat off some more races.
Put the meat in a bowl and add spices to the barbecue. Cut one onion into rings and knead well together with meat. Leave to soak for about 2 hours.
Cut the second onion and pickle with vinegar with the addition of a little water, pepper and salt.
First you need to put the onions in the hands for baking, then the meat, tighten on both sides and make two holes on top so that the steam comes out. Before you put the baking tray in the oven, you still need to cover it with baking paper so that the onion does not burn.
Bake kebab for 1.5 hours at 250 degrees.
