It's the simplest thing. Trim ends and halve. Toss with olive oil. (I use my hands to make certain they're coated evenly.) Single-layer them on a cookie sheet, cut side down. (I use that non-stick foil so that ) Top with fresh ground salt and black pepper. (I use fresh ground because they're coarser than pre-ground.) Bake in a 400 degree oven for about 20 minutes. I include the looses leaves that come off during trimming in the pan because they get really crispy; I consider them a treat.

The Veganomicon mentions throwing in some garlic cloves about 5 minutes before they're done but I've never wanted to because the sprouts are so good all on their own. And now I'm hungry for them. Guess I know what I'm having for dinner!
