In a crock pot place your pork shoulder or butt roast. Season the roast with the 1 Tablespoon of salt and 1 teaspoon of black pepper. Peel the garlic cloves and add to the crock pot whole. Dice the onion and add around the roast. Pour 1 1/2 cups of the Salsa Verde on top and around the roast. Add the Brown sugar on top. Cook on low for 6-7 hours or until the roast can easily be shredded. Enjoy!
