Preheat grill to medium to high heat.
Place salmon on a piece of aluminum foil, long enough to wrap salmon. (I place this on a cookie sheet, easier to handle)
In a small bowl mix garlic, mayo, lemon juice, basil, salt, and pepper.
Evenly spread over the top of the salmon.
Lay sliced lemons on top of sauce and salmon, see picture.
Enclose salmon in aluminum foil.
Place on preheated grill for 14-16 minutes.
While salmon is cooking preheat oven on broil.
When salmon is finished on the grill open aluminum foil, place in oven, broiling to the top for 2-3 minutes.
Remove from oven and serve with you favorite side veggie!
