My future SIL recently informed me, "You're in charge of the kielbasa from now on"...Even my picky niece, who will pretty much eat nothing but hot dogs and cheese quesadillas, likes my kielbasa.
Mix a bottle of honey barbecue sauce, 1 1/2 cups packed brown sugar, and a 20-oz. can of crushed pineapple (drained). Mix with 3 lbs. sliced kielbasa. Bake at 350 for 90 minutes.
You could also put it in a crock pot to keep it warm at the party.
