This is a dish our family likes to order in Kunming. The name literally means "Old granny potatoes" because it's well-suited to people who have no teeth. I've never seen how it's made, but I found the following description at http://www.etours.cn/china_city_guide/yunnan_travel_guide/dining/kunming_food.php : "Making method is very simple and popular for people of all ages. In fact we can think of it as a kind of mashed potato stir-fried with vegetable oil, chopped shallot and onion, and sliced green pepper and hams and so on. Assistant materials are added according to individual taste." With that description and my own memory of the dish to go on, here's a recipe!
