Fall Minestrone Soup

Dice onion, carrot, and celery into small pieces. Heat olive oil in a large pot over low heat.

Add diced onion, carrot, and celery to the oil. Cook gently until soft and translucent, about 8 minutes, without browning.

Chop leafy greens, zucchini, potato, tomato, and garlic. Add all to the pot with beef broth and rosemary.
