Hearty Fall Chicken Barley Soup

• 1 tablespoon extra-virgin olive oil
• 1/2 cup finely chopped onion
• 1/2 cup finely chopped celery
• 2 cloves garlic, divided
• 6 cups reduced-sodium chicken broth
• 1 rotisserie chicken, large shred
• 1/3 cup pearl barley
• 1 15-ounce can diced tomatoes
• 1 cup trimmed and diagonally sliced asparagus, (1/4 inch thick)
• 1 cup fresh or thawed frozen peas
• 1/2 teaspoon coarse salt
• Freshly ground pepper, to taste
• 1/2 cup lightly packed torn fresh basil leaves
• 1 strip orange zes

1. Heat oil in a large saucepan over medium heat; add onion and celery and cook, stirring, until beginning to soften, 2 to 4 minutes. Grate or finely chop 1 clove garlic; add to the pan and cook, stirring, until fragrant, about 1 minute. Add broth and barley. Bring to a gentle simmer. Cover and cook over low heat  about 20 to 30 minutes.
2. When the barley is done, add the chicken, tomatoes and juice, asparagus, peas, salt and a grinding of pepper; return to a simmer. Cover and cook over low heat until the asparagus is tender, about 5 minutes more.
3. Coarsely chop the remaining garlic clove. Gather basil, orange zest and the garlic and finely chop together. Ladle the soup into bowls and sprinkle each serving with a generous pinch of the basil mixture.
