Begin by preparing your Brussels sprouts, trimming off the ends and removing any wilted outer leaves. Using a mandoline or food processor, shave the sprouts into thin slices, aiming for a consistent thickness to ensure even texture throughout your Shaved Brussels Sprout Salad. Set them aside in a large mixing bowl, and admire their vibrant green color.

In your bowl with the shaved Brussels sprouts, drizzle in extra-virgin olive oil and freshly squeezed lemon juice. Add the pine nuts and dried cranberries, along with the optional pecorino cheese, if using, and snip the chives directly into the bowl for fresh flavor. Gently toss everything together until the ingredients are fully incorporated and every sprout is well-coated in the dressing.

Lightly season your salad mixture with sea salt and freshly ground black pepper. Use your hands or tongs to mix gently and distribute the seasoning evenly. The Shaved Brussels Sprout Salad should have a well-balanced flavor, so ensure you taste it and adjust the seasoning as necessary to suit your preferences.

Allow the salad to rest for about 15 minutes at room temperature. This step is essential as it enables the flavors to meld and the sprouts to soften slightly, enhancing the overall taste and texture of your Shaved Brussels Sprout Salad.

After resting, give the salad another gentle toss. You might want to drizzle a bit more olive oil for added richness or adjust the seasoning again with salt and pepper. Serve this colorful Shaved Brussels Sprout Salad immediately as a refreshing side dish or a light meal, and enjoy the compliments from your delighted guests!
