I ran across this recipe a few years ago (I think) on the Primitive & Rustic gals forum. I'm sorry I can not remember who posted it. At that time I didn't think it would be a dish I would like but I emailed it to my sister who just made it for the first time this year for Christmas dinner. I loved it so much I made it a few days ago. I'm not a big fan of pineapple but with the other ingredients it's just the perfect combination of YUMMY!
