First, remove the tough outer leaves of the artichokes and cut off part of the stems. Cut off about 1 inch from the tips. Cut artichokes in half lengthwise and scoop out the choke. Drop into boiling salted water seasoned with the juice of one lemon and one tablespoon olive oil. You may also roast the artichokes in the oven as shown in the picture . Cook for 30 minutes or until tender. Serve with a dressing of 1/2 cup olive oil and 4 tablespoons lemon juice, which is about the juice of 1 lemon. This is a super simple recipe and its not like your typical "salad." A salad in Greece can just be marinated vegetables.
