sweet potato pineapple mash: is served as a side with turkey (at our dinner they had turkey, mashed potatoes, mashed sweet potatoes (with pineapple bits), carrots & peas, brussels sprouts & bacon, stuffing, gravy and last but certainly not least cranberry sauce.
the sweetpotatopineapple mash (sppm) is quite sweet, but goes very well with the turkey.
i've never made it myself but found a few recipes online (there are many more)
- this is probably the closest to what we had:

these also sound worth a try:

if i tried it myself - i would probably steam or bake the sweet potatoes, mash em, add shredded fresh pineapple (the tart freshness should be good with the potatoes' sweetness), then add a little bit of butter(to make the flavours come out), and salt & pepper as needed and bake until hot
i don't think i'd add all the spices, as i love the flavour of the sweet-potatoes and don't really want to hide it.
