Pulled Pork Sliders (Slow Cooker)

Martina's new favorite. She eats like a bird and she ate three sliders this evening. We might have to start making this for her birthday every year. Hawaiian rolls are a must. The Walmart brand worked well. From Woman's Day.
* 1/2 cup apricot preserves
* 1 Tbsp cider vinegar
* 1 red onion, sliced
* 2 1/2 lb boneless pork shoulder, trimmed
* 2 tsp ground cumin
* Kosher salt and pepper
* 8 small rolls, split
* 8 leaves green-leaf lettuce
* Potato chips, for serving

Recipe Preparation

1. In a 5- to 6-qt slow cooker, whisk together the apricot preserves and vinegar; stir in the onion.
2. Season the pork with the cumin and 1/2 tsp each salt and pepper. Nestle the pork among the onions and cook, covered, until pork is tender and easily pulls apart, on low for 7 to 8 hours or on high for 5 to 6 hours.
3. Using 2 forks, shred the pork and stir it into the cooking liquid. Form sliders with the rolls, lettuce and pork. Serve with potato chips, if desired.
