Bring a large pot of water to a boil. Add kale leaves and cook for a minute, until kale loses its chalky taste. Drain well. Place kale, one chopped garlic clove, salt, pepper, extra virgin olive oil, water, artichoke hearts, cilantro leaves, scallions, and lemon juice. Process until smooth, scraping down the sides. Add a little more water if you like a thinner consistency.
