Tuna Salad with Egg and Potatoes

Boil the potatoes in salted water with their skins until soft (small potatoes take approx. 30 minutes). Then let them cool, peel, and halve or quarter them depending on their size.

Hard-boil the eggs for approx. 8-10 minutes, quench them, let them cool, and peel them. Then cut into wedges or slices.

Clean the green beans and briefly blanch them in boiling salted water until al dente. Immediately quench them in ice-cold water to retain their green color. Cut the cucumber into bite-sized pieces. Drain the tuna.
