Have you ever ate a whole jar / can / box of something?

I ate a whole bag of baby carrots the other day. I better have perfect vision on my next eye doc appointment too!

I’ve eaten a whole large pizza.

More than once I have consumed a jar of Peanut Butter in one sitting. Was almost addicted to it.
I would buy a Kilo of peanuts and blend them up with a teaspoon of Hot Chilli Sauce. Dems the old days though. A 375 gram jar lasts a week now.

At one sitting? Sure cookies and chips

When I "hide" food - I eat all of it- not usually all at once though

A jar of dill pickles as a kid. They've never been the same since. 🤢

tropical fruit salad

Yes, nutella

cherry pies

caviar. cheddar popcorn (orville)... chocolate milk!
i used to love peanut butter... oh, sigh.
