I haven't tried this but found the recipe and wanted to make sure I could find it again. I'll let you know how it goes.
sliced ham (deli meat works well)
1 can crushed pineapple--use all of juice and 1/2 of pineapple
1/2 cup brown sugar
Put juice, pineapple, brown sugar, and seasonings in a pot (not the crock pot). Heat just long enough to melt sugar. Pour a little of sauce on bottom of crock pot. Put ham in and pour the rest of sauce on top. Cook one hour or until warm.
