I cannot believe I even have them - but they have been found at Costco in Cabo San Lucas. I am taking them to friends' home for Thanksgiving dinner and need to prep ahead but I really want to roast them. Can I roast them ahead of time and then just put into the oven for a few minutes when the turkey comes out? And if so, should I kind of partially roast them at home first? We are having a very traditional turkey dinner here in southern Baja and I really want them to be good. Many thanks!!
