2 pounds sweet potatoes, peeled and cut into cubes
1/2 Vidalia onion, finely chopped
1 red pepper, seeded and finely chopped
4 green onions, thinly sliced
1/3 cup mayonnaise
2 tablespoons orange juice
1 teaspoon smoked paprika
1/2 teaspoon ground cumin
Salt and freshly ground black pepper
Add the sweet potatoes to a large pot of cold salted water. Bring to a boil over medium-high heat and cook the potatoes until tender, about 15 minutes. Drain the potatoes and let cool in a colander.
Once the potatoes are cool, transfer to a large serving bowl and add the onion, red pepper, and green onions.
