@mattly ah finally a man who understands the nuance.
Adding the BBQ sauce is good and good quality pineapple is key.
Pork and pineapple in the cookout style IS a good flavour combination.
Crappy canned pineapple can really ruin it and your basic ham + pineapple on tomato sauce isn't exactly compelling.
But when done well pineapple on pizza can be glorious.
