In a 4-to-6 quart slow cooker insert, whisk together whole berry cranberry sauce, sweet chili sauce, honey, fresh orange juice, orange zest, garlic powder, onion powder, and smoked paprika until well blended.

Add the Halal beef meatballs into the slow cooker. Gently stir with a wooden or silicone spoon until every single meatball is thoroughly coated in the glossy cranberry chili glaze.

Cover with the slow cooker lid and cook on LOW for 2 to 3 hours (or on HIGH for 1.5 to 2 hours), stirring once halfway through, until the meatballs are piping hot and the sauce is bubbly and thickened.

Once cooked, switch the slow cooker setting to "WARM" to keep the meatballs hot and ready for guests throughout your party.

Garnish generously with finely minced fresh parsley and fresh rosemary sprigs. Provide party cocktail toothpicks or skewers alongside the slow cooker or transfer to a festive serving platter!
