Vegetable Cabbage Soup

Heat oil in a Dutch oven over medium-high heat. Add onion; cook, stirring occasionally, until translucent, about 5 minutes. Stir in garlic; cook, stirring constantly, until fragrant, about 1 minute. Add cabbage, carrots and celery; cook, stirring occasionally, until the cabbage starts to wilt, about 8 minutes.

Stir in tomatoes, beans, broth, crushed red pepper, salt and pepper; bring to a boil over medium-high heat. Reduce heat to medium-low; simmer, uncovered, until the cabbage is tender, about 25 minutes. Remove from heat; stir in parsley and thyme. Garnish with parsley leaves, if desired.
