Season the pork chunks with salt, pepper, cumin, and cinnamon. Heat a skillet over medium-high heat and sear the pork until browned on all sides, releasing a rich aroma.
Transfer the browned pork to your slow cooker and add the minced garlic and chicken broth. Cover and cook on low for about 4 hours, or until the meat is tender and falling apart.
While the pork cooks, prepare the slaw by combining sliced apples and chopped kale in a large bowl. In a small jar, whisk together maple syrup, apple cider vinegar, and olive oil, then pour over the slaw ingredients. Toss gently until evenly coated and the kale begins to soften.
Once the pork is cooked and tender, use tongs to shred it directly in the slow cooker, mixing it with the flavorful juices remaining inside.
Warm some tortillas in a skillet or microwave. Fill each tortilla with a generous amount of shredded pork, then top with a hearty scoop of the apple kale slaw.
Serve the tacos garnished with extra sliced apples or fresh greens if desired. Enjoy the combination of tender pork and crisp, tangy slaw in every bite!
