The sauce for the kapsalon never goes directly on the chips, otherwise they very quickly get soggy. First chips, then the meat, some sauce, cheese, more sauce, salad is the proper sequence. Another vital ingredient is lashings of unsweetened chilli sauce.
There are also two varieties, lamb and chicken. Personally I find the combination of lamb and cheese uneatable, but the chicken version really hits the spot, especially if the salad is more imaginative than just lettuce.
