Steamed Brussel Sprouts

Fit a large pot with a steamer insert; fill with water to bottom of insert. Cover, and bring to a boil. Add Brussels sprouts, and season with salt; steam, tossing halfway through, until bright green and just tender, 6 to 8 minutes. Transfer to a bowl. Season with salt and pepper; toss with butter and chives. Serve immediately. Serve with butter or shredded cheddar cheese.
