In a bowl large enough to contain the arugula, whisk together olive oil, lemon juice, honey (if using), salt, and pepper until completely combined.
2 tablespoons extra virgin olive oil, 2 tablespoons freshly squeezed lemon juice , 1 teaspoon honey, ¼ teaspoon kosher salt, ¼ teaspoon coarse ground black pepper
Add arugula to the bowl, and toss until coated. Lightly stir in Parmesan cheese or garnish salad with shaved cheese and lemon zest, if desired.
1 container (5 ounces) baby arugula, washed and dried, 2 ounces shaved Parmesan cheese , zest of 1 lemon
This salad is best served immediately because the arugula wilts somewhat after it's dressed. It still tastes good but isn't as attractive.

Notes
Variations: If you're not a fan of arugula, use another tender green. Try different cheese, such as gorgonzola, blue cheese, or feta. You can add fresh herbs to the salad, fresh fruit, or vegetables such as thinly sliced radishes, cucumbers, tomatoes, etc.
Make ahead tips: Prepare dressing, wash and dry arugula, and shave the Parmesan cheese up to a day ahead. Store components of the salad separately in the fridge and combine right before serving.
