Salt the minced meat and place in the fridge for around 4 hours. Then, mix it with the black pepper and cumin. Thinly slice the onions and mix into the mixture along with 2 or 3 teaspoons of water. Mix all the ingredients well and let rest again in the fridge for 2 hours. Form into meatball or burger shapes and either fry them or barbecue them ... serve with salad or vegetables of your choice and, of course, don’t forget the cold glass of Bulgarian beer!
