Instructions

Thinly slice the Brussels sprouts into fine ribbons using a mandoline, food processor, or sharp knife; place in a large bowl.
In a small bowl, whisk together Dijon, lemon juice, vinegar, and honey. Slowly drizzle in the olive oil while whisking to emulsify. Season with salt, black pepper, and red pepper flakes (if using).
Pour the dressing over the shaved Brussels sprouts and toss, massaging lightly for about 1 minute to soften them slightly.
Add the apple matchsticks, sliced shallot, toasted walnuts, parsley, and Pecorino/Parmesan (if using). Toss to combine.
Taste and adjust seasoning with more salt or lemon if needed. Let stand 5–10 minutes to meld flavors before serving.
