1. Begin by gathering all ingredients and preparing your slow cooker by lightly greasing it with cooking spray or lining it with a slow cooker liner for easy cleanup.
2. Place the sliced kielbasa into the slow cooker, distributing them evenly along the bottom.
3. In a medium-sized mixing bowl, combine the chopped apples, brown sugar, apple cider, Dijon mustard, and garlic powder. Add salt and pepper to taste. Mix well to ensure all ingredients are fully combined.
4. Pour the apple and seasoning mixture over the kielbasa in the slow cooker, making sure that the sausage pieces are well-coated.
5. Cover the slow cooker with the lid and cook on low for 3-4 hours or on high for 1-2 hours, until the kielbasa is heated through and the flavors have blended together.
6. Once the cooking time is up, give the kielbasa bites a gentle stir to coat them in the sauce once again.
7. If desired, garnish with chopped fresh parsley to add a touch of color and fresh flavor just before serving.
8. Enjoy your Slow Cooker Apple Kielbasa Bites hot, dispensing them onto a serving tray with toothpicks or serving them over your chosen accompaniment.
Remember to keep them warm if they are being served at an event, as they are best enjoyed when the kielbasa is succulent and the apple bits are tender.
