I love Brussels Sprouts, so long as they're not boiled, and I confess I have never eaten liver and onions! I'm guessing I'd probably like it or at least not mind it, I'm a pretty non-picky eater.
My favorite recipe for Brussels Sprouts is this:
Take the brussels sprouts (preferably nice little ones--and fresh, never frozen) and cut them in half. Get a pan warm, and throw in the sprouts w/ some salt and pepper and about 2 pieces of chopped bacon (I use the center cut variety, lower in fat) stir them around, and when the brussel sprouts start to brown up a little, throw in a tbsp or so of minced garlic. When the bacon is cooked you're ready to go!
