Definitely pizza. A bit less than back in the days when I could eat pizza almost exclusively and never get fed up, but that's surely still the biggest one for me. When I was around 20, I'd eat on average a whole large pizza every other day or so, and if there were any leftovers, I'd make them my breakfast the next day.
There was that one year when I spent my whole Christmas holidays, new year and first week of January eating only pizzas and playing Halo. That's probably three weeks or so of living only on pizza. The good old university days.
Most pizzas are nowhere as unhealthy back home (paradoxically they can make for a rather balanced meal) as the calorie-bomb-style pizzas here in Canada though, so that's where I ironically started eating a more varied diet. Surprisingly, I love Hawaiian back home the most, but I don't like it anywhere as much over here. The pineapple taste here is completely different, I swear it tastes like an entirely different fruit that just doesn't go with a pizza that well. In Europe, we use Thai or African pineapples from former French colonies, which are much less tangy. Here they use South American/Carribean or Hawaiian ones, which weirdly taste very different.
As far as TV shows go, I was never into them much, so no guilty pleasures there. Except.. when eating pizzas, I used to watch either the Discovery channel or old cartoons. Think Nickelodeon or Cartoon Network of late 90s/early 2000s. That would be the ultimate homey experience for me. Yeah, so there's that. Abusing pizza while watching cartoons. I think that's what I'm going to do later today, for old times' sake. I just found some on Netflix!
