Moe, I've learned that almost anything will 'get you started,' most of the time!
Like both of you geezers, I remember almost all of those varieties that you've brought to mind. Like JiffyPop popcorn and its close cousin, 'aerosol cheese'....both of which were novelty items rather than gourmet fare, were still very much a necessity to the boys in our Scout troop.
On winter camps the cheese would freeze in their packs and not dispense at all....and the JiffyPop, which the boys seemed insistent on heating over a campfire that was so hot you couldn't get closer than 10 feet to it, was always burnt to a crisp with lots of blackened & unpopped kernels. 
As for the treatment of the problem of the frozen aerosol cheese....one kid used his hatchet to get at his stash.
.......but another kid, that I remember, particularly, solved the problem by nestling his can of sprayable queso in a bed of good hardwood coals at the edge of the fire.
The result, as you may have guessed, quickly gave everyone around the fire an unintended, but FREE sample!

I've been told that, the "almost anything can get me started" appears to be an endearing quality that people seem to like about me, well, that and the fact that I've managed to still be around and have memory good enough to remember allot of funny stories from my over three quarters of a century of living on this rock.
Cheese Whiz (Thanks Tony), probably not the healthiest stuff (akin to Velveeta I suppose) to eat, but again, like Velveeta it's handy and serves a purpose, funny how the mind lets you smell and taste things from your past that you haven't had in decades.
Talking about Jiffy Pop, it was a pretty popular item among kids and some older folks as well I suppose, but I never had a use for the stuff, I love popcorn, there's an electric popcorn maker sitting on the our farm table as I type this, I made up a huge bowl of the stuff night before last, my wife and I enjoy some of the British mystery shows on PBS, my wife records them and when we get a few together we make a night of it watchin Midsummer Murders, Doc Martin, Father Brown and a few others, and sharing a bowl of popcorn.
Back in the day my Mom and Dad made popcorn in a small stock pot, add oil, a cup of popcorn, put it on the stove, cover it with a lid, when it started to pop shake the pot, when it stops popping it's done, pure over some melted butter and a palm full of course salt and enjoy.
Even while in the scouts we always made popcorn in a pan or kettle of some kind, using Jiffy Pop was kind of like cheating, anyhow, the one and only (that I can remember) tine that we ever tried Jiffy Pop was one a leave peeping trip we took the kids on, it was a planned day trip into the Berkshires in western MA., it was a wonderful fall day and nobody really wanted to go home, so we drifted from MA. into NH., it got late so we pulled the pickup into a small campground for the night.
The Pickup had a camper cap on it and we always kept some sleeping bags and camping gear in the back, we also had a little food left from the sandwich stuff the wife had packed, well I'll tell you it may have been just about a hundred miles north of home but it was much colder than it was at home at this time of the year, we were camped a few miles from Franconia Notch and the Old Man of the Mountain and it got freezing a$$ cold in those mountains.
The place we were camped in had some of those big class A motorhomes parked not far from our site, and there was a nice little brook the ran right by our campsite, which was frozen solid when I got up that next morning, anyhow that night I built a respectable fire and we were crowded around it trying to store as much of the heat off the fire as we could while the wife made what was left of the sandwich stuff, and it wasn't much.
Well the lady from one of the monster motorhomes must have took an interest, because she came over to give us one of them Jiffy Pop foil pans, there were only five of us then, me, the wife, and three young ones, I thanked her and she didn't linger (it was cold).
The kids took the wrapper off the foil pan and put it over the fire, it didn't take long to start popping and within a minute or so we were left with a bloated foil pan full of steaming burned little lumps of what looked like charred punk wood, wolfy knows what I'm talking about.
So, after one of the coldest nights we've ever spent camping the sky finally brightened and we all piled into the cab of that F-250 and waited for the heater to start pumping out some warm, it was about 6:30 am. when the trucks cab started to show signs of warming and we pulled out of the campground, we ended up driving through those mountains until about 9:30 when the sun finally made it over those mountains and started giving off some radiant heat.
We spotted a small diner up ahead and I aimed the truck in it's direction and said to the family, I guess that's the last time you guys want to go camping at this time of the year, our oldest (about 12 yrs. old at the time said "No way, I want to come back next weekend, if we can bring a heater", it turned out to be a great trip after all, but we never did give Jiffy Pop another try.
