Preheat the oven to 425 degrees F. Combine the orange zest, ginger, soy sauce, orange juice, vinegar, sesame oil and honey together in a small bowl; set aside.
Fold 4 (16 by-12-inch) parchment paper squares in 1/2 lengthwise.
Evenly divide the bok choy, bell peppers, and bean sprouts among the 4 parchment packets. Season the vegetables with 1 tablespoon sesame-ginger marinade. Place a salmon fillet on top of the vegetables and season with the black pepper and an additional tablespoon of the marinade.
Fold the top half of the parchment over the fish, and overlap small folds along the open edge to seal. Brush each packet with olive oil. Bake for 8 to 10 minutes, until the parchment paper puffs up.
Transfer the parchment packets to plates. Carefully cut the packets open, avoiding the hot steam, and serve.
