1. Using a sharp paring knife, trim the outermost layer of leaves from each artichoke. Trim stems, and cut off top half of each artichoke. As you trim them, place them in a medium bowl; add lemon juice, and toss to coat.

2. Transfer artichokes to a medium nonreactive saucepan. Add enough cold water to cover artichokes by 1 inch. Using a small heat-proof plate, weigh down the artichokes to keep them submerged. Bring to a simmer over high heat. Reduce heat to low, and simmer artichokes until fork-tender, about 15 minutes. Transfer to a colander to drain.

3. Cut artichokes in half lengthwise. In a large skillet, heat olive oil over medium heat. Add artichokes in a single layer, and cook until hot, about 3 minutes. Add garlic and parsley. Cook, stirring occasionally, for 1 minute longer. Season with salt and pepper. Serve immediately.
