Preheat oven to 350°.
Remove white papery skin from garlic head (do not peel or separate the cloves). Brush with 1 teaspoon olive oil; wrap in foil. Bake at 350° for 1 hour; cool 10 minutes. Separate cloves; squeeze to extract garlic pulp. Discard skins.
Heat the remaining oil in a large saucepan over medium-heat. Add onion and salt; sauté 5 minutes. Add carrot and the next 4 ingredients (carrot through tomato paste); cook 5 minutes, stirring frequently. Add Vegetable Stock and beans; bring to a boil. Reduce heat; simmer, uncovered, for 30 minutes.
Stir in garlic and kale; simmer 10 minutes or until kale is tender. Stir in lemon juice and pepper. Garnish with parsley, if desired.
