Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Heat the olive oil in a large pot over medium heat. Add the diced onions and celery and cook, stirring often, for about 8 minutes until softened.
Add the minced garlic and cook for 1 minute until fragrant.
Stir in the diced tomatoes with their juices, the chicken broth and the pearl barley. Bring to a boil.
Reduce the heat to low, partly cover the pot and simmer for about 50 minutes, stirring occasionally, until the barley is tender.
Stir in the chopped parsley just before serving, then ladle the soup into bowls.

Fit is the average pairing score against tomato, onion, garlic, olive, chicken, celery, barley. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
