2. Shape rounded teaspoonfuls of bacon mixture into 3/4-inch balls. Place on a parchment paper-lined baking sheet; chill 1 hour.
3. Chop remaining 2 bacon slices. Microwave chocolate in a microwave-safe bowl at HIGH 1 to 1 1/2 minutes or until melted and smooth, stirring at 30-second intervals. Dip chilled bacon balls into chocolate. Place on a parchment paper-lined baking sheet. Immediately sprinkle tops with bacon. Chill 30 minutes before serving.
