In 5-quart Dutch oven, heat 2 teaspoons of the oil over medium heat. Cook onions, carrot and celery in oil 9 to 12 minutes, stirring occasionally, until carrots are just tender. Stir in garlic, salt, dried herbs and pepper; cook about 1 minute or until garlic is fragrant. Add beans and broth. Increase heat to high; heat to simmering. Cover; reduce heat to medium-low, and simmer 15 minutes. Stir in baby greens; simmer 4 to 5 minutes or until greens are tender.
