Oven Roasted Brussels sprouts

So many people say they hate Brussels sprouts.  Perhaps if you boil them or commit some other atrocity they are nasty, but roasted like this are sweet and divine.

1 bag or stalk Brussels sprouts
2 T olive oil
½ tsp salt
½ tsp pepper

Trim any dried ends of sprouts.  Toss with oil, salt and pepper.  Roast in oven at 400 until soft and golden brown – 20 minutes?
