Discovering the grating disk on my food processor many years ago was a eureka moment for me—ten minutes later I was grating and then sautéing every vegetable I could put my hands on. Talk about convenient! Baking a whole sweet potato takes about an hour, but sautéing the grated potato takes only fifteen minutes from start to finish—and you end up concentrating the flavor to boot. This recipe dresses up your potato with Southwestern ingredients, but there’s no reason not to go Asian (add ginger and soy) or Italian (add sage, brown butter, and pine nuts) as the mood strikes you. For that matter, you could swap out the sweet potato and use butternut squash instead.
