Preheat the oven to 350F. Mix the sweet potatoes, honey, cinnamon, and salt together in a large mixing bowl. In a separate bowl, beat the eggs, then gradually beat in the sugar and vanilla. Pour the eggs into the potato mixture and mix well. Add the pecans, if desired, and pour into the pie shell. Bake for 1 hour or until a knife inserted in the middle comes out clean. Yield: One 9-inch deep-dish pie.
