Cut octopus into 2-3 pieces.
Шаг 2
Peel potatoes, cut into medium cubes, boil in salted water.
Шаг 3
Drain the water, put the potatoes on the fire to dry. Add octopus and mussels to warm them up.
Шаг 4
Chop garlic, add finely chopped dill, olive oil, mustard oil and mustard. I didn't add salt: there's enough salt in boiled potatoes and marinated seafood.

Cut tomatoes in half. Place all salad ingredients in a bowl, add dressing, pepper and mix gently
