I've had it, which is why I'm not a fan of it, but if someone orders one, it needs to at least have jalepenos as well. I do like grilling it or otherwise cooking it with a bit of rum - good topping for ice cream or short cake.
Green bell peppers are awful - if I want that much chlorophyll flavor in my food I'll trim some grass from the back yard. I WILL cook up red, orange and yellow bell peppers in any number of dishes, though - hot Italian with peppers & onions is a nice dish.
I also don't mind the anchovies, though I do prefer to mince them or use them to add a bit of umami to sauces and such. The best way to use them on pizza isn't whole fillets, but minced fillets mixed into the sauce or lightly sprinkled across the pie.
Green or black? Black wouldn't make it worse; green would make it exponentially more unpalatable...
