Tuna salad with egg and potatoes

Boil the potatoes in their skins in salted water until tender. Smaller potatoes cook for approximately 30 min. Let them cool and cut them into halves or quarters depending on their size.

Boil the eggs hard. This takes approximately 8 minutes from the start of boiling.

Briefly boil the green beans in salted water. Drain and immediately transfer to cold water. Cut the cucumber into pieces. Drain the brine from the tuna.
