Cut the ends off the Brussels sprouts. Cut large Brussels sprouts in half. Smaller ones can be left whole. Discard the ends and any tough outer leaves.
Using a food processor with the slicer attachment, shred the Brussels sprouts.
Place a large sauté pan over medium high heat. Add olive oil and let it heat for about 30 seconds. Add the shredded Brussels sprouts. Add salt and pepper and sauté until the Brussels sprouts are bright green and some have started to brown.
