From the site and Wikipedia.
This is Louisiana's Official State Meat Pie. It is a beef and pork pie with a moderately spicy seasoning or you can get it more spicy with additional cayenne pepper "for that extra kick." They come baked inside of folded pie crust.
They even have a meat pie festival every year in Natchitoches, Louisiana, in September.
Wikipedia has it as a regional dish from northern Louisiana with ground beef and pork, onions, peppers, garlic and oil as ingredienats all baked in a pie shell.
