I can't do cold leftovers. If it is something I would eat hot regularly, it needs to be reheated when I am eating leftovers. I just really like hot foods though. Leftovers also always make my life easier. Make a big meal at the beginning of the week and then it can last me a few days (this week it is taco meat). It all tastes about the same to me from the time it's first cooked to the time I eat it as a leftover, so I don't think I can say one food is the best as a left over than another food.
