Add the xylitol, paprika, cumin, garlic powder and salt to a small bowl. Mix to combine.

Add the pork shoulder to the slow cooker and sprinkle over the seasoning mix. Use your hands to rub the mixture into the pork.

Add the water, mustard and balsamic vinegar to the slow cooker.

Cover and cook on slow for 8 hours until completely cooked through and tender. Shred the tender meat with two forks.

Before serving you can prepare the slaw. Add the cabbage and onion to a small bowl and toss to combine. Whisk together the sour cream, tomato puree, paprika, garlic powder and salt in a separate bowl.

Spoon the sour cream mixture over the vegetables and stir well to combine until completely coated. Set aside.

Remove the stalks from the mushrooms. Wipe the mushrooms clean and brush all over with a little olive oil.

Heat a grill to high and place the mushrooms on a grill rack, cap side up. Grill for 6-7 minutes until tender and cooked through.

To serve, divide the shredded lettuce between two mushroom halves. Divide the pulled pork between the two mushrooms and top each with half the slaw. Slice the dill pickles in half lengthways and arrange on top of the slaw. Top with the remaining mushroom ‘buns’ to finish.
