allrecipes, I don't have a grill so I made changes to cook it in the oven.
1/4 cup maple syrup
3 tablespoons butter, melted
1 fresh pineapple
2 tablespoons chopped macadamia nuts
2. Combine syrup and butter; set aside.
3. Slice the pineapple about 1/4 inch.
4. Place pineapple on rack over tinfoil lined cookie sheet (I use a cooling rack--make sure yours is safe enough to use at high temperatures).
5. Brush pineapple with maple butter and cook for 10 minutes. Turn pineapple, brush on other side and cook for another 10 minutes or until heated through. Sprinkle with nuts. Serve with remaining maple butter.
*However you grill pineapple, it is delicious. I used peanuts in place of the macadamia nuts. They were good, but if you don't have any, they are not mandatory. Everyone at the table loved it. I'd also like to try another version with canned coconut milk.
