In heated oil, fry onion and garlic for 2-3 minutes. Then add meat. Stir-fry everything together for 7-10 minutes. Then add tomato paste, stir and simmer for another 5 minutes.
Place the potatoes and meat base in a deep saucepan. Pour boiling water over everything, so that the water does not completely cover the products, and put on the fire. As soon as the dish boils, add salt, pepper and mix everything. Reduce the heat to minimum and simmer the roast for 30-40 minutes.
Add the bay leaf, stir and remove from heat after 5 minutes. Leave the roast for another 10 minutes under the lid, then serve.
