This is a simple grilled peach crisp that's sweet and indulgent!
If your bbq or grill surface is big enough you can place the peach slices and the baking sheet of the crisp topping on at the same time. The topping will only take 5 to 7 minutes until it starts melting and getting golden brown. You can toss it a couple of times and watch it doesn't burn. Once the sugar is bubbling and everything looks darker brown in color remove the baking sheet from the grill and place the topping onto another sheet or on a plate to cool completely. It will cool in a more solidified piece and you can break it up with a fork into a crisp crumbly topping.
The peaches shouldn't be moved once placed on the grill until you're sure they have the grill marks on them, then flip once to do the other side of the peach wedges.
