"I served this at a neighborhood potluck last night and everyone at the table had seconds. Would definitely serve it again. The only changes I made were to use green onions (4 sliced onions) and as I thought the quantity might be short I added a package of herb instant potatoes to stretch it. No one was the wiser. The dish was very popular with the crowd!"

"I made this for Thanksgiving at work and everyone loved it! I didn't use a whole onion since some people do not like onions. I did add some onion powder and topped half of it with green onions. Delicious!"

"I made this a week ago at a church Thanksgiving dinner and now I'm making it for my Thanksgiving dinner at home. I like it not only for its flavor but because it reheats well, which is hard to do with regular mashed potatoes."
