Beef and Pasta Vegetable Soup

Directions

1. In a pressure cooker over medium-high heat, brown beef on both sides in oil. Add the water, carrots, celery, potato, onion, garlic and seasonings. Close cover securely; place pressure regulator on vent pipe. Bring cooker to full pressure over high heat. Reduce heat to medium-high and cook for 15 minutes. (Pressure regulator should maintain a slow steady rocking motion; adjust heat if needed.)
2. Remove from the heat. Immediately cool according to manufacturer's directions until pressure is completely reduced. Discard bay leaf. Remove beef with a slotted spoon; when cool enough to handle, remove meat from bones. Discard bones and dice the meat.
3. Return meat to pan. Add the beans, tomatoes and zucchini. Bring soup to a simmer. Stir in macaroni. Cook, uncovered, for 8-10 minutes or until macaroni and zucchini are tender.
