Start by preparing the ground beef. Heat the sesame oil in a pot and add the ground beef. Cook until browned. Finely chop the leeks and garlic, and add them to the cooked beef. Add the tomato paste and cook thoroughly. Then add the tomato puree, hot water, crushed red pepper, and salt. Stir to combine. Once the sauce starts to thicken, add the egg noodle cakes on top. Mix the noodles well with the sauce once they are cooked. Serve with cheese or yogurt on the side. Enjoy!
