Place the wedges in a large bowl and drizzle with oil. Season with salt and pepper and toss to combine. Place on the grill, cooking on all sides until cooked through, about 10 minutes total. Remove and drizzle or brush with a bit of maple butter, sprinkle with salt and parsley to finish.
In a bowl, blend the butter, maple syrup and allspice together until light and smooth. Refrigerate and use as a spread or melt and drizzle over pancakes, grilled sweet potatoes or popcorn. Yield: 1/2 cup
