One of the easiest recipes with the widest appeal, that I have so far found, is Chicken and Olive Tajine. This is often made with french fries on top but I add a twist sometimes by making zucchini fries.
Cover pressure cooker and allow to cook for 45 minutes. Remove from heat and open pressure cooker, checking the chicken to ensure it’s cooked through. It should be tender and falling off the bone.
