Preheat an outdoor grill or grill pan to medium-high heat, about 400-450°F. Scrub the grate clean and oil it lightly.

Trim, peel, and core the pineapple. Cut it into 1/2-inch rings or half-moons and pat the pieces dry with paper towels.

In a small bowl, stir together the melted butter, brown sugar, cinnamon, salt, and lime juice until the sugar is evenly moistened.

Brush both sides of the pineapple with a light layer of the glaze. Let excess drip off so the sugar does not burn on the grill.

Place the pineapple on the hot grate and cook for 3-4 minutes per side, until sizzling, glossy, and marked. Move pieces to a cooler spot if they darken too fast.

Transfer to a platter and sprinkle with lime zest and mint if using. Serve hot as a dessert or side dish.
