1 pineapple, core removed, sliced 1/2 - 3/4" thick
In a shallow baking dish, drizzle enough maple syrup to just cover the bottom.
Layer the sliced pineapple on top of the syrup, and cover with an additional layer of syrup (rub it in with your fingers to distribute it if needed).
Let it sit for 5-10 minutes.
Grill pineapple slices over medium heat, about 7-10 minutes per side, until grill marks are visible and pineapple is heated through.
