Place the water in a large stock pot over high heat.
Add the potatoes to the stock pot. Bring to boil and then reduce heat until the water is at a slow boil.
Cook the potatoes about 10 – 15 minutes until slightly soft in the middle. They should be firm when squeezed.
Remove from heat and drain water.
Add the olive oil, roasted garlic, vinegar, celery, salt, pepper and green onions. Toss well. Serve warm.
