Place all of the ingredients into the pressure cooker and cook on high heat. Once it starts steaming reduce to low heat and pressure cook for 5 minutes.
Once the time is up, stop the heat. When the lock button naturally unlocks, open the lid.
Turn on the heat, and check the flavor. Adjust to your liking.
Top over your boiled pasta and it's complete. You can top with cheese or mix it in, and that's also delicious.
Story Behind this Recipe
I wanted to eat a rich, delicious meat sauce that could be made easily, so I did some research. Since I have a small child, I decided to use a pressure cooker as it doesn't require much effort.
You can also use celery and shiitake mushrooms, which are delicious. For the hot weather season, I recommend using plenty of vegetables since it softens while cooking. If you have leftovers, you can freeze it, or use it in lasagna or doria. Our family freezes it, then enjoys eating it with pasta a few days later.
