Preheat your grill to medium-high.
Pat your fillets dry and then season them to taste with the lemon pepper, bay seasoning, and salt. Press the seasonings into your salmon.
Butter the bottom of your salmon fillets, and throw a little butter on your onion rings, try to keep them whole if you can.
Grill the salmon and the onions, butter side up, directly over the heat for about 2 to 4 minutes. Flip once and cook for another 2 to 4 minutes.
Serve with rice and whatever veggies you have. Garnish with some snazzy and sexy sesame seeds. Take a bite of salmon with some of that grill-caramelized onion.
