Pat I too LOVE brussel sprouts roasted and I too cut them in 1/2. So many people are afraid of them, but they're fabulous. This is gonna sound weird, but they're almost like a delicacy.
Whenever I make them, which is about once a week, and bring them to the table my 17 year old daughters eyes light up and she gets all excited and says (everytime without fail) "Hello my little friends". So yeah, she likes them too.
I also use cooking spray for roasting. It's only zero calories for like a few second spray. I spray more then that, but it gets way better coverage then just drizzling on oil and I figure whatever calories I use on it, are calories well spent.
