In a Dutch oven or 5-quart saucepan, heat oil over medium. Add ginger and garlic; cook 1 minute until fragrant. Add bok choy stalks and celery; season with salt and pepper and cook, stirring frequently, until crisp-tender, 5 to 7 minutes. Add scallions and bok choy greens and cook until wilted, about 3 minutes more.
Heat broiler with rack 4 inches from heat. In a small bowl stir together hoisin, ketchup, mustard, and 1/2 teaspoon lemon juice. Place fish on a broiler pan or broiler-proof rimmed baking sheet. Season with salt and pepper. Brush tops with hoisin mixture. Broil until fish is glazed and opaque throughout, 5 to 7 minutes.
Add remaining lemon juice to greens. Spoon vegetables on four plates and top with fish fillets. Serve immediately.
Cholesterol is MANUFACTURED by OUR bodies by the FAT we eat. Fish is a GOOD THING! to quote Martha!
sbt121-You are way off about cholesterol. Cholesterol is very important to our health. I recommend doing some research, start with Weston A. Price.
I didn't really care for this dish. Followed it pretty carefully but it was not as tasty as it sounded. I have to add that I disagree with the comment below. Fish oil is recommended by heart doctors because it is so good for us. It is the types of food sources and exercise that are, together, important for bringing down cholesteral.
If you really want to lower your cholesterol, cut out ALL cholesterol from your diet. This includes fish. Yes, they are one source of omega3's, but they are also a source of cholesterol. There are plenty of sources of omega3's that don't include cholesterol - such as flaxseed and hemp milk.
