Pat the pork roast dry with paper towels and season with salt and pepper on all sides.
Set the slow cooker to saute mode (or skip this step), add the avocado oil, and sear the pork on all sides.
Add the red onions around the pork, followed by the potatoes, and finally the apple slices and garlic.
In a large measuring cup, whisk together the chicken stock, apple cider,honey mustard, apple cider vinegar, and salt and pepper. Pour the mixture into the slow cooker.
Add the bay leaves and thyme springs and set the slow cooker to low for 6-8 hours or high for 4-6 hours.
After cooking, slightly pull apart the pork with tongs and serve on a bed of the red potatoes. Drizzle the juice over the top.
