In a medium saucepan, stir together the peach preserves, chili paste, and Worcestershire sauce, if using.
Heat the sauce mixture over medium heat and add the sliced kielbasa.
Cook over medium heat for 5 minutes or until the kielbasa is heated through, stirring frequently to coat the kielbasa in the sauce.
Serve warm as an appetizer or part of your dinner. Use any extra sauce for dipping!
