I usually make it a point to warm up any restaurant left-overs before devouring them, but sometimes certain restaurant left-overs are best eaten when cold. It's not even about laziness it's more about preference. I actually enjoy eating a combination chow-mein that I pick up at my local mom & pop Chinese food eatery. I don't even worry about warming it up, I just grab a fork & eat it cold. I love the way the bits of meat & noodles do a happy dance in my mouth. I just like it. There's nothing better in my opinion. What leftovers do you like to eat the next day, cold?
