Mediterranean Chicken and Wheat Berry Salad

In a 6-qt. multifunction electric or stove-top pressure cooker combine broth, tomatoes, and wheat berries. Lock lid in place. Set electric cooker on high pressure to cook 35 minutes. For stove-top cooker, bring up to pressure over medium-high heat; reduce heat enough to maintain steady (but not excessive) pressure. Cook 35 minutes. Remove from heat. For both models, let stand 15 minutes to release pressure naturally. Release any remaining pressure. Open lid carefully. Using a slotted spoon, transfer wheat berry mixture to a large bowl; discard liquid in cooker. Cool to room temperature. Stir in next four ingredients (through mint). Follow the instructions above in step 3 for making the dressing and serving.
