For the ham you will need a ham and a can of pineapples. I usually would take pineapple slices but I had chunks that I had bought for something else that I never ended up making, so I used those.
Slice the ham the way you like it. I like mine not too thick, I find it more flavourful. I used a 750gr ham and used half of it. The other half went in the freezer. There was three of us for dinner and I had some left for my lunch.
Put the sliced ham in an oven proof dish and put the whole can of pineapple on top (juice and all). If it's slices you might want to arrange it all nice. Give it a little shake to disperse the juices.
Put in the oven at 350 or so for about half an hour. Mine doesn't look all esthetic because it's chunks.
I served my ham with scalloped potatoes, the recipe will follow shortly!
