Heat a large skillet to medium heat and add remaining 2 tablespoons olive oil. Add garlic and sauté for 30 seconds. Add artichoke hearts and sauté for 10 minutes or until lightly browned and warmed through, stirring occasionally and being careful not to burn the garlic or the oil. Add juice of 1 lemon, thyme, parsley, salt and pepper. Carefully stir in roasted tomatoes. Season to taste with additional lemon, salt, or pepper if necessary. Serve.
