Pasta Carbonara, done properly though. One of the few carb meals I miss. In a past life I would have said lasagne, chips, and french bread to mop up but I couldn't face it now.
Normally something like a McDonald's, Burger King or KFC does me, though we've recently had some new Zapatista burrito bar places open up in Newcastle, basically like Subway except Mexican, and not fking minging. The stuff from Zapatista is absolutely spot on.
My diet's pretty good generally, but there's no way I could give up a massive dirty Papa Johns or Dominos every so often. It has to be the largest size they do and I'd never rule out a family meal deal.
The large is usually gone in 15 mins. There's no 'WE' in food!
Dolmas/Dolmades - prefer hot home made lamb mince ones, but the rice only ones in cans are still fantastic. I only buy a can at a time as I just know I would end up living off the stuff otherwise. That or minced lamb keema - fart-tastic the next day if suitably spiced, too.
