Instructions:
- Place sliced kielbasa sausage in the slow cooker.
- In a bowl, mix brown sugar, honey, soy sauce, Dijon mustard, garlic powder, and black pepper until well blended.
- Pour the sauce over the kielbasa, stirring to coat each piece evenly.
- Cover and cook on low for 3-4 hours or high for 2 hours, stirring occasionally, until sausage is heated through and sauce is thickened.
- Serve warm as an appetizer or over rice for a hearty main dish.
