Wash the fish, pat dry and rub on both sides with salt, chilli, lime juice and olive oil.
For the salsa, you can peel the peach, but you don`t have to, dice the onions and peppers very small and put them in a bowl. Chop the mint. Add the lime juice and honey to the salsa. Season with salt and chilli. Let it steep a little and then season to taste. Refrigerate.
Grill the fish on the grill over direct high heat on the meat side for about 6 minutes until it can be removed from the grid. Then turn and grill for another 2 - 3 minutes, depending on the degree of doneness you want.
Serve the fish with the salsa. Baguette goes well with it.
