Wash artichokes, remove any overly tough stem or outer leaves, slice in half lengthwise.
Add water and 1 tablespoon to large bowl, soak artichokes for 2 minutes to prevent oxidization.
In small bowl, whisk together olive oil, remaining 1 tablespoon lemon juice, garlic, herbs and salt until combined.
Remove artichokes from water, pat dry. Dunk each to coat well in olive oil mixture -- rotate to get all sides. Place coated olive oil on rimmed baking sheet.
Bake for 15 minutes, flipping half way through.
Remove from oven and sprinkle with Parmesan cheese, if desired. Serve warm
