Chop the onion and garlic. Fry them in a frying pan with vegetable oil, tomato paste and ground black pepper.
Wait until the frying begins to thicken, stir until it reaches a uniform consistency and remove from heat.
Add the medium-sized potatoes to the pot with the beef. Cook together for another 5-10 minutes.
Add washed rice and adjika to the pan. Cook for another 10-15 minutes. At the end, add the finished fried mixture to the kharcho. You can add fresh greens, spices and herbs. Cook for 2-3 minutes until done.
Leave the finished kharcho in the pan under the lid and let it brew for 10-15 minutes. Pour the soup into serving bowls. If desired, garnish with fresh herbs or 1 slice of lemon.
