In a small bowl, combine the salt, cumin, oregano and pepper. Trim the excess fat from the roast (you want some fat, just remove any big chunks). Press the seasoning mixture into the roast on all sides.
Pour the broth into the bottom of a slow cooker. Place the roast inside and arrange the orange slices over the top. Cook on low for 8-10 hours (preferable) or on high for 6 hours.
Carefully remove the roast from the slow cooker and discard the orange slices. Use two forks to shred the meat.
If desired, place the shredded meat on a heavy, rimmed baking sheet or broiler pan. Turne the oven broiler to low and position an oven rack about 4 inches below the heat. Place the tray of meat under the broiler and allow some bits to get crispy, but watch carefully so it does not burn.
Garnish with any of the optional toppings and place into lettuce or cabbage leaves to make primal-style and low carb tacos.
Cuban Unwich – makes 6 servings
If you haven’t broiled the Slow Cooker Carnitas , you should do so for the unwich to bring out maximum flavor. After broiling, remove the sheet but keep the broiler on.
Arrange the pickle slices on top, followed by the ham. Use the back of a spoon or a spatula to carefully spread the mustard on the ham slices. Sprinkle the cheese in an even layer over the ham.
Return the sheet to the broiler to brown the top, about 1-2 minutes. Keep a close eye on the cheese, you want it to melt and start to bubble and brown, but definitely not burn.
Enjoy with a knife and fork or wrap in lettuce leaves, cabbage leaves or collard greens.
