Peel and cube the sweet potatoes and put them in a large pot. Cover with water, bring to a boil and boil until tender, about 5 minutes. Drain and set aside to cool.
While the potatoes are cooling, in a medium bowl, mix the mayonnaise, yogurt, scallions, red pepper, chives, orange zest, apple cider vinegar and hot sauce. Add the cooled potatoes to the mixture, and toss until the potatoes are fully coated. Add salt and pepper to taste. Best served chilled.
