8 ounces raw Italian pork or chicken sausage (casings removed if necessary)
1 medium onion, chopped (about 2 cups)
3 large carrots, peeled and chopped (about 2 cups)
Salt and black pepper
6 cups stock or water
1 (14-ounce) can diced tomatoes
½ cup pearled barley (see Tip)
6 cups/about 8 ounces tender greens, like spinach or baby kale
2 tablespoons red wine vinegar or apple cider vinegar
Grated Parmesan and fresh herbs (optional), for garnishing
Steps
Heat a medium Dutch oven or other heavy-bottomed pot over medium. Add the olive oil and swirl to coat the bottom of the pot. Add the sausage, pressing it into a thin layer that covers the bottom of the pot. Cook, undisturbed, until golden brown on the bottom, about 5 minutes. Flip the sausage and break it up into bite-size pieces, then cook until golden brown all over, stirring occasionally, about 5 minutes more. If there is a large amount of fat left in the pot after browning the sausage, remove all but about 2 tablespoons.
Add the onion and carrots, season with salt and pepper, and cook, stirring occasionally, until the onion is translucent, about 5 minutes.
Stir in the stock, tomatoes and their juices and the barley, scraping the browned bits from the bottom of the pot. Bring to a simmer, then turn the heat down to low and cook, stirring occasionally, until the barley is tender, about 30 minutes.
When ready to serve, stir in the greens and cook until bright green and slightly wilted, about 2 minutes.
Add the vinegar, taste and season with salt and pepper as needed.
Divide among bowls and garnish with Parmesan and fresh herbs, if using. (The soup will keep, refrigerated, for up to 3 days. The barley will absorb some liquid as the soup sits, so loosen any leftover soup with a bit of water or stock.)
If using regular (hulled) barley, add about 15 minutes to the simmer time for the barley to become tender.
