I get this question a lot. I don't know if it's intimidation that people ask before they tell me what they cook! Or if it's a yay! I trumped the chef moment!
First off let's go back a few years when I was still officially working in the industry, single-ish, no kids, and only had to worry about one and only me. I would honestly have coffee for breakfast, maybe throw in a apple or whatever I had actually in my fridge. Then heading off to work I would actually eat a meal if there was a break in the day.
If not in all honesty I would eat simply, either it would be cereal or toast when the time to go home came along.
Craving anything fancy just didn't happen but if it did it would be on a day off. Cooking more than a basic meal after a shift was a far cry from reality
I am in no way saying this is every chef in the industry at all but when your cooking everything and I mean everything you just don't want to eat it.
