Bitter radicchio and tender Bibb lettuce create a crisp foundation for this bold, nutty salad. You'll blend toasted walnuts, fresh lemon juice, and garlic into a rich, creamy vinaigrette that coats the greens beautifully. Crumbled Gorgonzola adds a sharp, pungent bite to balance the earthy crunch of extra walnuts and fresh chives. It's an elegant starter that looks impressive but takes just minutes to toss together.
