I don't get why vegan and vegetarian food are highlighted here. People eat plenty of packaged or highly-processed meats, too. If anything, most raw items that don't require cooking are probably vegan, and there is no shortage of low-prep ones.
Remote work has made it easier than ever for many people to cook at home. Before the pandemic, meal prepping was a pretty convenient way to do it. A couple of hours a week can get you very far.
Barbazoo seems to me to be talking about the opposite of the tech scene, the 90% of people who don't have (or want to waste) an hour after work to cook dinner. Or even worse, take a half an hour away from sleeping every day to have time to cook breakfast, all for dubious benefit.
Will processed, quick foods hurt you more than sleeping an hour and a half less a day?
Some small subset might have to make hard choices about sleep versus cooking. Not 90%. Most are choosing something else over cooking.
It won't make it faster (wall time), but it reduces your effort to virtually zero. Dump the steel cut oats/milk/water in, push the magic button, and come back in 25 minutes. I've been eating this daily for breakfast for a couple years and it's great.
No continuous stirring to prevent scalding the milk, no slightly burned milk welded to the bottom of your pot, etc.
The recipe I like, fwiw: 2 parts (I use 1/2 cup) Bob's Red Mill steel cut oats; 3 parts whole milk; 2 parts water. 10 minutes on high pressure.
I don't think any fake meat is really satisfying enough for most people to eat it the way some omnivores sometimes eat animal proteins (as the main food for most meals). But I suppose it takes all kinds.
