Nutrition data and methodology
Nutrition values are based on the official McDonald’s Slovenia McChicken page, which lists 437 kcal per serving and 233 kcal per 100 g. The approximate 188 g sandwich weight is calculated from those two published calorie values.
McDonald’s states that its nutrition data are based on average values from European suppliers and that portions, preparation, ingredients, regional differences, seasonal differences, and product changes can affect the values.
