Now that I no longer have to deal with landlords, a proper pizza oven is on my garden wish-list. OTOH my OH has a long list of other jobs for house and garden that take priority - apparently she rates warmth, waterproofing, and structural soundness over proper pizza on demand...
Also, there's nothing wrong with pineapple on pizza. I wouldn't put it on a classic Neapolitan-style base, but ham and pineapple is a good sweet-salty combo and I won't be told otherwise.
