Fish salad with potatoes is a dish that gives scope to the cook’s culinary imagination. You can boil or fry the potatoes, add canned or salted fish. If you want the salad to be as healthy as possible, boil the potatoes in their jackets. The peel is a protective layer that, during heat treatment, retains more vitamins inside the tuber. Nutritionists note that the cold vegetable has a glycemic index of 50, therefore, it is useful even for diabetics in moderate quantities.
