Boiled potatoes..Do not over boil the potatoes, leave them a bit firm then dice them into big cubes.
Chopped green onion
Ground black pepper
Mix the potatoes with the above ingredients, the vinegar is to give the salad some acidity so just use a splash of it and not too much. You can add the ingredients in any amount you like to suit your taste. Even though I didn’t add in my potato salad but if you add olive oil in this salad it will make it even better. Serve the potato salad warm or cold.
