Place quartered potatoes in a large stock pot and cover with cold water and a good pinch kosher salt. Bring to a boil and cook until potatoes are fork tender, 7-8 minutes. Strain and let potatoes cool slightly.
In a large bowl, whisk together hummus, lemon juice and olive oil. Fold in cooked potatoes, scallions, parsley and mint. Check for seasoning and adjust accordingly.
Serve room temperature or chilled.
