Sweet potatoes are so versatile! I love them with just a little sweet and a little crunch! So will you!
Preheat oven to 425°. Line baking sheet with parchment paper. Place sweet potato planks flat on baking sheet. Brush each side with melted butter. Roast for 7-8 minutes.
While planks are roasting. Add walnuts, pecans, cinnamon, ginger, cloves sea salt, syrup and remainder of butter in a mixing bowl. Mix well.
Remove sweet potatoes from the oven and top each plank with the walnut mixture. Spread in an even layer.
Return sweet potato planks to the oven. Bake for 5-7 minutes until the walnut mixture is brown and crunchy.
Each plank is serving. Let cool slightly and serve.
