Allrecipes Community Tips and Praise 

" I made this with my Thanksgiving leftovers and I think it was better than the meal," says Dana. "I used the green bean casserole instead of the mayo and put in a layer of corn. Everyone loved it!!"

"This was a huge hit," according to Allrecipes Allstar SunnyDaysNora. "Simple to throw together and a great (and versatile) way to use leftovers. My daughter is a picky eater and she gobbled her serving up and asked me to put it in her lunch the next day!"

"Very moist and full of flavor," raves Allrecipes Allstar Love2CookMommy. "It was extremely easy to make. This recipe doesn't call for seasonings because you're using leftovers. If you make it without leftovers, season it to taste."
