In a large saucepan, saute the onions, carrots, celery and red pepper in oil until tender. Add garlic; cook 2 minutes longer. Stir in the water, tomatoes, peas, bay leaf, bouillon, basil, thyme, cumin, pepper and, if desired, pepper sauce. Bring to a boil. Reduce heat; simmer, uncovered, for 15 minutes.
Meanwhile, cook orzo according to package directions; drain. Stir orzo and turkey into soup; heat through. Discard bay leaf. Sprinkle with cilantro. Freeze option: Freeze cooled soup in freezer containers. To use, partially thaw in refrigerator overnight. Heat through in a saucepan, stirring occasionally and adding a little broth, water or milk if necessary.
