"Just cheese on toast"?

fighting words from the Guardian:

"...I can't help wondering whether such pizza fanaticism is actually a tragic case of diminishing returns: that no matter how good a pizza can be, the edible world is a wide place, with more to offer than a single dish. Treating pizza as a gourmet product defies the dish's own history, it defies logic and reason and a lifespan measured in years rather than millennia. It's only cheese on toast, after all."
