I'll play along. Like the others here, left to my own devices I'd bust out any of the multiple camp stoves I have, or take an old coffee can and make a hobo stove like I've been meaning to do, and get my cookin' on. But assume I didn't have these things, and had to make do.

Well, most canned foods are already cooked. They may not be their most appetizing at room temperature, but they are edible. Hot dogs are also precooked (at least, all the ones I am inclined to eat) so there's that too. Eat those first, of course, because your fridge is out. If I'm not in an apartment that resticts it, I may have a propane grill to use for grilling/cooking. Even if all I keep in my pantry are baked beans and non-condensed soup I am in business for a little while, at least. Certainly enough to keep me away from the PODs until the grocery store spins back up.

As far as actual recipes for this stuff... well, I've never thought of it. Aside from a salad every thing I would think to cobble together would require heat because in a pinch I'd still have that to work with. Even jamboree mulligan needs heat to cook.
