It is handy they come in single serving size. One bag per meal.
Cheese and Tomato pizza.
Tater tots
Veggie egg rolls
Pizza King pizza (only found in central Indiana, as far as I know)
I will eat any of these until I burst, which is why I rarely buy the first two, and I have no access to the third.
I once - when I was about thirteen - ate an entire bowl of shredded beef that my mom had made for tacos for the whole family. I don’t know what I was thinking. Why would there just be a big ol’ bowl of beef for the taking lying around that didn’t have another purpose?
We had to make a change in dinner plans. My parents teased me about it for years.
But now I’m a vegetarian, so we’ll never know if I could repeat that feat.
I could probably eat more pineapple than anyone else. Even after it starts hurting, I’ll just keep eating. Mmmm, acidic fruit.
What I really, really want is just the peanut butter from the middle of these - I could eat as much as were in front of me.
Joe
Potato chips and cookies. If I open a package, it’s sure to be empty within fifteen minutes. Even if I’m not hungry any more, I still can’t resist.
Mayonnaise. Although I don’t do it anymore, as a kid, I ate many, many sandwiches that were just two slices of bread with a thick layer of mayo. I actually fantasized about getting my name in the Guinness Record Book for mayonnaise eating. Never actually tested my limits, though.
Ice cream. I have to buy it in pint sizes, cause I could eat a gallon of the stuff.
I don’t have to ask my SIL the corn freak this question, I once saw her eat 14 ears of corn on the cob at one sitting, wiping up the excess butter and corn bits with corn bread that she also ate.
Watermelon. I have actually stopped buying whole watermelons. 
Guinness
So what did you do after the appetizer was taken away?
2 or 3 dozen? PAH! I rather surprised the waitress at a bar we went to to watch the NFL playoffs a few years back by ordering an extra dozen after polishing off the 50 they had brought me.
Why yes, I am a fat bastard.
Oh you’re on then. Not that It’s a good idea, but I can easily do 20+ pints in an evening if I pace myself. We should get a sponsor to cover off on the beer though, this could get expensive.
For me, besides Guinness I’d have to say that it’s either pistachios or salt water taffy.
Caviar. Seriously.
Not even the good stuff, but the $25/lb stuff you can buy in Brighton Beach. With a little water and vodka, I ate a pound of it on a dare. If there had been more, I would have eaten more.
Cheese. Almost every other foodstuff on earth is just a medium for cheese. For most things, if you can’t put cheese on it, there’s little point in eating it.
Hmmm, 20 is quite a lot for an evening but if we started at about 2pm then thet should be ok. It also depends on if I’m playing pool or not 
€6:50 ($9) a Guinness here in Paris so we had better go somewhere else a little easier on the pocket
Oh, and we’ll need an independent witness, preferable from this thread, to supervise (and go to the bar for us).
Dried apples [although I’m sure I’d regret THAT quickly!]
Blue Bunny Bunny Tracks ice cream
Swedish fish
Chocolate
And to drive us home as well. 
There’s a place down the road from me that does $2 pints (€1.37!) on Tuesdays, so say when you can make it. 
Pao de queijo (too lazy to actually type it properly). They’re these little Brazilian cheese puffs, and they are to die for. I can easily eat a whole batch. I love them with black coffee for breakfast.
Bacon and crab legs, which I know others have mentioned, are also on the list. I could eat bacon until I have a massive coronary, and all-you-can-eat crab leg places HATE me.
Fresh, ripe local strawberries, with or without turbinado sugar, I could eat until they’re gone, no matter how many there are.
When I’m sick, I guzzle grapefruit juice like Joey Chestnut.
$2 ? Wow…I didn’t know your economy was doing that bad ! 
I’ll ask the wife later on. She’ll have to know which state we’re talking about though. We just came back from a Texas-Arizona-California tour.
I’m about 45 minutes west of Chicago. Bring it on.
