In a medium mixing bowl, combine sweet potatoes, 1 tablespoon coconut oil, maple syrup and ½ teaspoon salt. Stir in red-pepper flakes and cook for 30 seconds, then stir in turkey, 1 teaspoon salt and ½ teaspoon pepper and raise heat to medium-high. Transfer to a bowl, stir in remaining green onions and cover to keep warm. Uncover and add ¼ teaspoon salt and ¼ teaspoon pepper and continue to cook until the chard is just cooked through. Add turkey to each bowl, then top with roasted sweet potatoes, sautéed chard, edamame, walnuts and avocado.
