Place salmon fillet on a sheet of tin foil.

Cut butter into chunks and place in salmon. Next sprinkle as little or as much as you want of lemon pepper. Place mint leaves all over the salmon.

Form a pocket with your tin foil around the salmon. Place directly on the grill. Around ten minutes open the packet and check with fork to see if its done.

Salmon should be flakey. And do not flip as all the butter will go out of the foil. Once the salmon flakes apart it is done. Time varies on how hot the grill is.
