1. Rinse chicken and cut into 1-inch cubes. Cut linguisa into 1/2-inch slices.

3. Discard all but 1 tablespoon fat from pan. Add onions, carrots, and celery. Stir occasionally until onions are limp, about 5 minutes. Add broth, chicken, linguisa with juices, tomatoes, cabbage, and lemon peel.
4. Seal cooker. Following manufacturer's instructions, bring to maximum pressure (15 lb.); adjust heat to stabilize cooking rate. Cook 10 minutes. Release pressure quickly, running cold water over pan.
