Peel the sweet potatoes and beets. Then use a spiralizer to cut the veggies into long curly strips. Use a pair of kitchen shears to cut the pieces into manageable lengths.
Mix the beet and sweet potato ribbons together in a large bowl. Then cut the scallion tops on an angle to make long rings. Sprinkle the salad with scallions and pepitas. Serve with your favorite vinaigrette.
