Combine all of the salsa ingredients in a medium bowl. Refrigerate until ready to use, or go ahead break out the chips.
Preheat your grill on high heat.
On a baking sheet without sides, create a "tray" large enough for your salmon pieces out of heavy duty aluminum foil. Place the salmon on the tray.
In a small bowl, combine the chipotle powder, sugar, salt and pepper. Divide the mixture between the four pieces of salmon, making sure to cover them well.
Slide the "tray" onto the grill and close the lid of the grill. Reduce the heat to medium and allow to cook for about 15 to 20 minutes, depending on how hot your grill gets.
When done, carefully slide the tray back onto your baking sheet.
Serve as is, or with the salsa on top!
