Preheat oven: Preheat your oven to 400°F (200°C).
Prepare foil packets: Cut four large pieces of aluminum foil. Place a salmon fillet in the center of each. Arrange broccoli, carrot, and bell pepper around the salmon.
Make honey ginger sauce: In a small bowl, whisk together honey, soy sauce, grated ginger, garlic, sesame oil, salt, and pepper. Pour over salmon and vegetables.
Seal packets: Fold foil over salmon and vegetables, sealing the edges to make a packet.
Bake: Place foil packets on a baking sheet and bake for 15–20 minutes, until salmon is cooked through and vegetables are tender.
Serve: Carefully open packets, garnish with lemon slices and sesame seeds, and serve immediately.
