Preheat oven to 400°F (200°C). Place meatballs on parchment-lined baking
sheet; bake in oven 15 to 20 min., or until browned.
Meanwhile, combine jelly, barbecue sauce, maple syrup and cayenne pepper in large saucepan set over medium-high heat; bring to a boil then reduce heat to medium. Stir in meatballs. Cover, stirring occasionally, another 8 to 10 min. until meatballs are tender.
For easy entertaining, keep warm in slow cooker for serving.
Garnish with finely chopped parsley, chives or green onion.
