In a crock pot, place the boneless pork roast or chops into the bottom. Season with salt and pepper. Cook the pork on low heat for 5-6 hours, or until fork tender. Once the pork is tender, drain all of the grease and juices from the crock pot and discard. In a bowl, whisk together the sauce ingredients and pour all but 1/2 cup of the sauce, over the pork. If the pork is shred-able, then shred the pork into thin strips. Put the lid back on the crock pot and let it simmer for 30 minutes.
For the slaw, slice the carrots into really thin strips. Place the carrots into a bowl. Chop the cilantro and add to the carrots. Peel the cucumbers and dice them into small pieces. Add those to the bowl. Slice the red cabbage super thin and add to the bowl. Toss the slaw in the half cup of the remaining sauce. To prepare the sandwiches, place a generous portion of the shredded pork onto the bottom of the bun. Spoon some of the slaw on top of the pork. Serve the sandwiches warm and with extra Sweet Thai Chili Sauce.
