In a small saucepan, combine bourbon, brown sugar, soy sauce, ginger, and garlic. Bring to a simmer over medium heat and cook until slightly thickened, about 10 minutes. Remove from heat and set aside.

Prepare the Salmon

Preheat the grill to medium-high heat. Place the soaked cedar plank on the grill for 3-5 minutes until it starts to smoke.

Glaze the Salmon

Place the salmon fillets on the cedar plank, skin side down. Brush generously with the bourbon glaze.

Grill the Salmon

Close the grill lid and cook the salmon for about 15-20 minutes, or until it flakes easily with a fork.

Prepare the Vegetables

While the salmon is grilling, toss the green beans, mushrooms, and pearl onions with olive oil, salt, and black pepper. Grill in a vegetable basket or foil for about 10-15 minutes until tender.

Serve

Once the salmon is done, remove it from the grill and let it rest for a few minutes. Serve the salmon alongside the grilled vegetables.
