In a non stick pan, add the onion and ground pork, breaking up the meat with your spatula, and sprinkle with the ½ tablespoon of Italian seasoning. Cook, turning often until no pink remains and the meat is cooked through.
While the pork is cooking, in a large saucepan, add the tomato paste, water, sugar, and 2 tablespoons of Italian seasoning, place on low heat and whisk together. Simmer until hot, stirring often. When hot, add the butter and stir in. Taste and adjust as needed for salt or sugar.
When the pork is done, if any excess fat in the pan, drain that off, then add the cooked pork to the sauce and mix together. Taste, and adjust as needed with salt and or sugar. Continue to simmer on low heat for another 15 minutes.
