who was first to put pineapple on pizza
... in the year 1521 the Italian Antonio Pigafetta (nice name) discovered pineapple in Brazil on his circumnavigation of the globe. Being homesick he made pizza and not having tomatoes and cheese added pineapple and tuna.  In 1493, Columbus first brought the pineapple back to  Renaissance Europe that was largely devoid of sweet foods,  including fresh fruit. The pineapple's exotic nature and sweetness  soon made it an item that soon acquired both popularity and  curiosity for centuries after its European arrival.
