Preheat your grill to a medium-high heat and lightly brush oil the grate.
In a small bowl, whisk together the brown sugar and cinnamon.
Pour the cinnamon/sugar mixture into a large resealable plastic bag and add in the pineapple slices (or rings) and shake until well coated evenly.
Remove the coated pineapples and pour the remaining cinnamon sugar mixture back into the bowl, add the honey in and mix.
Grill the pineapple wedges on the your preheated grill for about 4 or so minutes per side, brushing each side with more of the mixture as they cook with a basting grill brush.
