Use a food processor or sharp knife to thinly chop/shred the Brussels Sprouts.

Heat olive oil in large skillet over medium high heat. Add Brussels sprouts, season with salt and pepper, and sauté for a few minutes, stirring only occasionally to allow them to crisp a little. Add garlic then cook for 30 seconds.

Drizzle a little water over the top to steam them a little (cooks them quicker), stir and continue to cook until tender.
