Peel the eggplant, cut it into a small cube and fry it in vegetable oil until it is ready. Ready-made eggplants flip in a colander to remove excess oil, and season with salt.
Finely chop the onion. Wait for the eggplants to cool down. Peel the potatoes and grate them on a coarse grater.
In a salad bowl, put the grated potatoes and onions on top.
