Start by adding the little smokies or cocktail sausages to your slow cooker.

In a bowl, mix together the barbecue sauce, grape jelly, and Worcestershire sauce (if using) until well combined.

Pour the sauce mixture over the smokies in the slow cooker. Stir until the smokies are well coated with the sauce.

Cover and cook on low for 2-3 hours, or until the smokies are heated through. Stir occasionally to ensure that all smokies get evenly coated in the sauce.

Once done, you can leave the slow cooker on the 'warm' setting if you're serving these at a party. Provide some toothpicks or small forks for your guests to serve themselves.

Enjoy your Crock Pot Little Smokies as a perfect appetizer or party snack!
