How to Make It
Stir together tomatoes, potatoes, onion, Worcestershire sauce, vinegar, mustard, thyme, salt, tomato paste, cocoa, and red pepper in a pressure cooker. Place chicken on top of tomato mixture. Seal pressure cooker lid, and bring to high pressure. Cook for 25 minutes.
Release pressure according to manufacturer’s instructions. Transfer chicken to a large plate or bowl; cool slightly, about 15 minutes.
While chicken cools, stir tomato mixture well, and reduce heat to medium to maintain a low simmer. Stir in lima beans, corn, and black pepper; cook until vegetables are warmed through, about 2 minutes. Remove and discard chicken skin, and pick chicken meat from bones. Discard bones, and stir chicken meat and scallions into tomato mixture.
