@The_Almighty_Kek @GolfCartLady the problem with the watermelon is that it still has the rind on it. Otherwise I would try it. Kiwi might be good in the same way pineapple is, but I've never had cooked/grilled kiwi so I don't know how much it it's sourness remains.
Banana pizza is actually a thing in some countries and they really like it. I would give it a shot. I feel like most stuff is probably good on pizza if prepared the right way, you just have to understand what you're eating and know it's not going to taste like a traditional pie.
@BadOptniks @GolfCartLady @The_Almighty_Kek they are! I've eaten them a few times to try it out. Just not something I really like, personally. Maybe they would be better cooked too idk.
