I don' t think it would be called "gyros", then

Me too, but not that disgusting thing that most so-called "Italian Restaurants" serve. This is some kind of American thick, soft bread with too much cheese and greasy ham. That is absolutely disgusting pizza. REAL pizza is consisted of a thick layer of crispy bread, some cheese -in the original version, this was Mozzarella- (not too much, just to cover the bread), tomatoes and oregano.
Well, I like pizza that has salami or peppers on it, though under conditions -I don' t think that a lake of fat on the cheese is the most healthy -not to mention delicious- thing in the world-.
I particularly insist on the oregano and garlic part. Those two ingredients give pizza an extraordinary taste.
It' s not our fault, nobody forced you to abstain from meat. If you cannot stand it, simply don' t do it. Personally, I would advise you to reconsider the effect religion has on your life.
