This root vegetable hash is a little bit sweet and a little bit spicy, just like Martha herself ;) If you can't find celery root, replace it with other root veggies like carrots, parsnips or rutabaga, and of course, feel free to adjust the spices to your taste! For a one-skillet meal, crack a few eggs on top and cook, covered, for another 8-10 minutes until the eggs are set, or serve the hash as a side dish next to some eggs, bacon and fresh coffee.
