Heat a large pot over medium-high heat for 2 minutes or until hot. Add oil and heat until oil is hot, about 1 more minute. Add about half of the meat in a single layer and sprinkle it with some of the salt.
Sear it until it is well-browned, about 2 minutes. Flip it and sear it on the other side. Remove the seared meat to a plate and repeat with the other half of the roast.
Add all the meat back to the pot. Add the crushed tomatoes to deglaze the pot and scrape the bottom of the pot well to get all the good flavor off.
Add remaining ingredients and mix well. Cover pot and turn heat to low. Simmer about 3 hours, or until meat is tender.
Remove meat to a plate. Shred with two forks, or allow it to cool about 10 minutes and shred with your fingers.
