Sweet Potato Hash Stuffed Portobello Mushrooms

Preheat oven to 425 degrees F.

Remove the stems from the portobello mushrooms. Set the caps aside and chop the stems.

Lightly brush the portobello caps with 1 tablespoon oil. Sprinkle with 1/4 teaspoon salt and 1/4 teaspoon pepper. Place on a rimmed baking sheet and roast until soft, 10 to 15 minutes. Keep warm.

Meanwhile, heat 1 tablespoon oil in a large skillet over medium heat. Add sweet potato and water. Cover and cook, stirring occasionally, until just cooked through, 6 to 8 minutes. Uncover and stir in the remaining 1 tablespoon oil, the chopped portobello stems, apple, bell pepper, shallots, poultry seasoning and the remaining 1/2 teaspoon salt and 1/4 teaspoon pepper. Cook, stirring, until soft, about 5 minutes. Stir in walnuts and parsley. Fill each mushroom cap with about 1 cup filling.
