Mix the salt, orange peel, everything bagel seasoning, mustard, lemon juice, and butter together in a bowl large enough to also fit the salmon.
Place 3-4 salmon filets in bowl with marinade and coat fish with it. Place in refrigerator for 2 hours.
Preheat Bull Grill to medium (approximately 350 degrees) and place salmon on Bull cedar plank . Turn off 1/2 the burners leaving 1/2 on medium heat. Place the Bull cedar plank on the side that is off. This will cook the salmon using indirect heat.
Cook salmon to desired temperature and remove the plank from heat. I use the Bull Plank Saver to extend the life of my cedar plank.
