This is my own recipe of potatoes with chicken hearts and mushrooms, made in the oven. But although it is made from traditional ingredients that are used in Moldova. It took me about 40 min. But in the end, it became very tasty and gentle taste. So here it is...

The ingredients are:
8 huge potatoes
1kg of chicken hearts
300 gr of mushrooms

The method of preparing:
Cut the potatoes as it is shown in the pictures and put the in the pan. Than add some spices. The second level should be of chicken hearts, there is no need to chop them. Just put them the way they are. Than cover it with onions.
Another slice should be of mushrooms, follow the pictures. Also add spices.
And again cover it with potatoes. The last step is the mayonnaise.
What is important that there is no need to add any water in it. The hearts will eliminate their own sous and that will be enough. Put it in the oven for 30-40 min.
