You may need to add a touch of water to the pan if the salsa is too thick.
The idea is to cook the meat until it is hot and the salsa has reduced into a sauce that covers the meat.
This will take a few minutes.
At this point you can use the meat for dozens of applications such as filling for tacos, topping for grain dishes, topping for any kind of rice and bean bowl, topping for salads and so on.
