Yes, you can spiralize Brussel sprouts. The trick is to get good sized sprouts with stems on the ends. Using the slicing blade, the Spiralizer replicates a mandolin (only safer!) and quickly produces a pile of thinly shredded Brussel sprouts.
An online search will yield a number of recipes using shredded Brussel sprouts. I like to simply sauté them using bacon and dried cranberries.
4 slices of bacon, chopped
5 cups shredded Brussel sprouts
salt and freshly ground pepper
1 TBS good balsamic
1/8 to 1/4 cup dried cranberries.
1. Chop 4 slices of bacon into pieces. Fry until crisp.
2. Add about 5 cups of shredded Brussel sprouts to the pan. Sprinkle lightly with salt and pepper. Toss to combine with the bacon and sauté ( medium heat) until the sprouts soften.
An alternate technique is to add 1/4 cup of water to the pan. Cover and cook over medium heat for a couple of minutes. Uncover the pot to finish the cooking.
3. Add a tablespoon of balsamic and some dried cranberries. Toss to combine.
