Preheat the oven to 325° F. Arrange the roast in the bottom of a large, oven-safe Dutch oven.
In a blender, blend the olive oil, tomato paste, tamari/soy sauce, vinegar, honey, ginger, chipotle, paprika, thyme, salt, and pepper until the chilies are chopped. Pour the sauce over the roast, tossing to coat. Snuggle 1 ½ cups pineapple around the roast. Pour over 1 cup water. Cover and roast for 2 ½ to 3 hours or until very tender.
Meanwhile, make the salsa. Mix 1 ½ cups chopped pineapple with the avocado, jalapeño, cilantro, and lime juice.
Crank the heat on the oven up to 425° F. Uncover and cook the roast for 10 minutes, until deeply caramelized on top. Shred the meat using two forks.
To make the bang bang sauce, combine all ingredients in a bowl.
Serve the meat and pineapple over bowls of rice. Top with the pineapple salsa and bang bang sauce. Enjoy!
