"Italian, paleo, omg, ragù! This was simply amazing. We are at our lake house for the summer and our friends came over. I had a super busy day and while at the butcher deciding what to make, the pork butt looked amazing.
I did serve this dish with a creamy polenta. I am Italian! What can I say... if you want to keep it paleo, then serve with sauteed vegetables or sauteed garlic spinach (I do that a lot).
This freezes well and taste even better the next day! You can also prepare this meal in your slow cooker."
Heat a large Dutch oven over medium-high heat; add oil. Stir pork into the hot oil and cooking, turning often with tongs, until pork is evenly browned, 10 to 12 minutes. Pour chicken broth over the pork and scrape any brown bits of food off the bottom of the Dutch oven using a wooden spoon; stir in garlic, Italian seasoning, and bay leaves.
Mix tomatoes and tomato paste into pork mixture, stirring and pressing paste along the side of the Dutch oven to help dissolve it. Reduce heat to medium-low. Stir, cover, and cook for 2 1/2 hours.
Remove Dutch oven from heat and shred pork into the tomato sauce using 2 forks. Add mushrooms; cover and simmer for 1 hour more. Remove bay leaves.
