I love it. Baked, with pineapple like a ham; fried (with a slice of cheese for a hot sandwich; or instead of bacon or sausage with eggs..
But my favorite way, is run it through a meat grinder (or dice it very finely if you don’t have a grinder handy), mix with mayo or salad dressing, a dab of mustard and sweet pickle relish for a cold sandwich spread, (sliced celery and/or chopped onion is also good in it ).
I can eat that twice a day for a week without getting tired of it, although after about a week I need to take a break from it for a month or so.
You are right. Spam makes a great base for “Ham Salad”. My Mom did this recipe without telling anyone to gauge family reaction. We all thought it was very decent ham salad. Then she sprang the true content on us. She liked to do this sort of thing for laughs. Fact of the matter is it tastes better and has more flavor than some ordinary hams when used as a ham salad base.
