On a hot grill, place peaches flat side down and cook for about5-8 minutes. Check to make sure the peach is soft and grill marks are showing. You can opt to flip them and cook them for a couple more minutes on their round sides to get them really melty.
Remove from grill and top with a heavy sprinkle of cinnamon and another good drizzle of honey.
Serve warm with a scoop of vanilla bean ice cream!
