Spiral Chicken Noodle Soup

1 pound boneless skinless chicken breasts, cut into 1/2-inch pieces
1 large onion, chopped
4 celery ribs, sliced
2 medium carrots, sliced
4 garlic cloves, minced
2 tablespoons butter
2 tablespoons olive oil
1 teaspoon dried basil
1/2 teaspoon dried oregano
1/8 teaspoon pepper
3 cans (14-1/2 ounces each ) reduced-sodium chicken broth, divided
1 can (14-1/2 ounces) diced tomatoes, undrained
6 ounces uncooked tricolor spiral pasta
1/4 cup all-purpose flour

In a large saucepan, saute the chicken, onion, celery, carrots and garlic in butter and oil for 5 minutes. Stir in the basil, oregano and pepper until blended. Set aside 1 cup broth. Gradually add remaining broth to the pan. Stir in tomatoes. Bring to a boil. Reduce heat; cover and simmer for 45-60 minutes.

Return to a boil; stir in the pasta. Reduce heat; simmer, uncovered, for 10-13 minutes or until pasta is almost tender. Combine flour and reserved broth until smooth. Stir into pan. Bring to a boil; cook and stir for 2 minutes or until thickened. Makes 6 servings (about 2 quarts).
