Sprinkle the pork butt generously with salt, black pepper and about a tablespoon ground cumin. Place in a slow cooker.
In a medium bowl, whisk together the salsa, peanut butter and remaining tablespoon cumin. Pour into the slow cooker over the pork butt. Cook on low for 8 hours, or until fork tender.
Remove the pork butt from the slow cooker and shred with 2 forks. Serve in bowls over the Mashed Potatoes, topped with a ladle of the cooking liquid from the slow cooker.
Garlic Mashed Potatoes :
Add the butter to a medium pot and place over medium-low heat. Once melted, add the garlic and cook until the garlic flavor is infused into the butter, 2 to 3 minutes. Add the mashed potatoes and mix to combine. Cook until the mashed potatoes are heated through, about 5 minutes. Top with the scallions and serve.
