Preheat the broiler.

Combine sea salt and black pepper in a small bowl.

Rub the salt and pepper mixture onto the skin side of each fish fillet.

Broil the fish, skin-side up, until the skin is browned and crisp.

Turn the fish and cook until browned and cooked to your desired doneness.

Cover the fish to keep it warm.

Heat sesame oil in a wok or large skillet over high heat.

Stir-fry the onion, garlic, and ginger until the onion has softened.

Add the salted black beans and stir-fry for 1 minute.

Add the green pepper, red pepper, green onions, snow peas, and broccolini.

Stir-fry until the vegetables are just tender.

Stir in the oyster sauce, lemon juice, and 1/2 cup of water.

Cook, stirring, until the mixture thickens slightly.

Add the baby bok choy and bean sprouts.

Stir-fry until heated through.

Serve the fish on top of the stir-fried vegetables.
