Cut pork roast in half (so it doesn't take quite as long to cook). Place in slow cooker with the fat pad on top.
Whisk together honey mustard sauce ingredients in a bowl or measuring cup and pour over the top of the roast.
Cover with the lid and place a dish towel over the top (so the heat doesn't escape). Cook on low for 8-10 hours or until it easily shreds with 2 forks or a pair of tongs.
Remove bone if present and any large chunks of fat, discard those. Mix shredded pork with sauce in pot to coat well and serve on slider buns!!
