Whaaat? Yous crazy 
I love putting chocolate candy in fridge/freezer. But it’s not meant to be “warm” really I don’t think. But M&Ms from the freezer = amazing.
Chili, any Mexican food, all Thanksgiving leftovers (including potatoes, gravy and lima beans,) rice, almost any casserole. Come to think of it, I’ll eat almost anything right out of the fridge, except a raw egg!
Asparagus and Brussels sprouts. I prefer them hot, but I do enjoy them cold.
I second both of these. When I make them, I leave a little in the pot and over the course of the rest of the evening, “finger-food” them bit by bit out of the pot.
I like hot scrambled eggs as well as the next guy, but find I also like the taste if they’ve been allowed to cool or even get cold. Being a fairly slow eater, this happens to me a lot.
I like roast beef right from the fridge. Rip off a piece of cold beef, a hunk of crusty bread, cut some aged cheddar and see heaven.
Not at all. One of my favorite breakfasts is cold keema naan used to shovel up slightly-congealed saag paneer or malai kofta.
The deliciousness is totally worth the day-long indigestion. 
Cold meatloaf is the best. My wife will make a meatloaf and then refrigerate the whole thing so that we can have sandwiches the next day. You have to let the flavors blend overnight.
I love coffee hot or cold, but I can drink it black if it’s cold, which is nice when I’m feeling lazy.
Baked beans right from the can.
I LOVE cold steak, too. I can’t decide which way is best.
Frozen corn, still frozen. Mmmmm. Little icy nuggets of joy.
It’s an entire meal of chilly goodness!
My first thought wasn’t for foods that had cooled down from when they had been hot, but foods that, while processed, are still frozen. (Though in the case of one they have been precooked.)
Chicken pucks
French Fries
Both direct from the freezer are great summer noshes.
Quick-cooking oatmeal in soymilk is strangely pleasing when I skim a spoonful or so off the top prior to microwaving it for the requisite 1 minute 20 seconds.
I have once or twice been tempted to chonk down the entire bowl uncooked, but so far, I have refrained for fear of painful bloating. Need I worry?
Oooh, my favorite is cold fried okra. YUM!
Iced coffee and leftover cold pizza are close seconds.
Cold pizza, Chinese food, Thai food, curries and Indian food are all just as good cold the next day. I munch steamed or roasted asparagus, brussels sprouts and cooked carrots out of the 'fridge. Also barbecue, especially ribs. Eggplant Parmesan. Stir fry. Rice, risotto, mashed potatoes, pasta!
I won’t eat soups cold, but most leftovers are pretty good chilled.
Do cookie dough, cake and brownie batter count?
Except leftover butternut squash soup, yum!
The curry you bought from a takeaway last night but couldn’t be bothered to eat tastes great cold and slightly dried up the following morning even with a hangover I kid you not.
This may sound strange, but I actually don’t really like pizza cold. Seems like everyone else does, though!
I don’t like cold pizza either. I don’t even like it lukewarm.
