Start a day ahead of time with the vinaigrette by mixing together some extra virgin olive oil, fresh lemon juice, champagne vinegar, minced shallot, and salt and pepper. For the asparagus use your vegetable peeler to shave each spear individually into long thin shavings then set aside in a bowl. This part doesn't go very quickly, a glass of wine helps.
Before serving toss the shavings together with the vinaigrette then salt and pepper to taste. And depending on what else you’re having some toasted pine nuts or shaved Parmesan are nice additions.
