This may seem like a no brainer to some, but I am assuming there is folks that do not know how to do this.
Where I live, Nakhon Si Thammarat Province, I can get minced pork at Tesco in town, there is no beef offered, and certainly no ground or minced chicken. Well one day I was going to make me a pot of Chili using minced pork (minced is just a courser grind of ground meat). But alas, when I got to Tesco, they were sold out of minced pork, so I just picked up some pork butt and figured I would make a slow cooker something. I got home and told my wife the mince pork was sold out, so I got several large pieces of pork butt. My wife said no problem, about 10 minutes later, she handed me a large bowl of minced pork and asked is that enough.
I asked her to show me how she did this as I always used a hand grinder when I was growing up. Large chopping block (think the large wood, thick, discs you see at the markets) and a cleaver. About 3 minutes of effort and you have minced anything, keep chopping and you have ground. It is really that easy!
I have a couple of chicken recipes lined up I am going to try using ground/minced chicken, as well as next time I order beef, I am going to mince some to make some good beef burgers.
Update 25 Nov 2016, I have purchased an electric meat grinder, Thai family is amazed at the speed. There is 3 plates for fine, medium, and course ground. It can grind 1 kilo per minute with the fine plate, bit faster with the course plate. I no longer buy minced pork, I grind everything myself and can control the fat content.
