1. 1 kg. potatoes (I used 5 potatoes)
2. 1 onion, sliced
3. Juice of 1 lemon
4. 1/2 cup olive oil
5. salt, pepper
6. Parsley, finely chopped
7. A few ripe olives, pickled in vinegar
Boil the potatoes whole in salted water. Peel, slice and place them in a salad bowl. Add the rest of the ingredients and stir well.
And let me make it clear that this is the first time I have made potato salad without mayo.
