1 pound baby bok choy, trimmed, leaves seperated
4 scallions, halved then cut into strips
6 oz shiitake mushrooms, stems trimmed, halved if large.
8 thin lemon slices
4 skinless striped bass or halibut fillets (about 6 oz each)
2 tbsp olive oil
Preheat oven to 400f.
Divide bok choy among 4x 16in long pieces of parchment paper. Top with scallions and mushrooms. Season with salt and pepper. Top with 1 lemon slice, 1 bass fillet, then another lemon slice and drizzle with 1/2 tbsp oil. Season with salt/pepper again.
Bring long sides of paper together and fold 3x to make a seem. Tuck ends to secure.
Place packets on a rimmed baking sheet and bake until fish is opaque throughout and vegetables are tender, about 15 minutes. Serve immediately.
