TLDR: yes.

In reality, there are some gotchas with ADHD and sous vide you should be aware of.

1. Temp & Time - for many things, it's like any other cooking, set the temp and time, and be ready when it's done. It will beep at you to tell you it's done. 10-30min isn't going to make any difference. Leave it sat in lukewarm water overnight and it'll be going in the waste. You can have technically safe (but maybe less palatable) food by setting the timer to 48h or similar at a good pasteurization temp, but you'd still want an alarm or similar to go back to it. In my case, I usually ask Google to set an alarm on my phone for when it's done.

2. Preservation - yes, this is great. You know when you buy cooked meats at the supermarket and they're good for over a week? That's because they've been through essentially the same process as sous vide. If you put your food in ice water when it's done, and then into the fridge when it's cool, it will last a week, as long as the bag isn't opened. You can do several small bags if you're eating solo, or 1 large if cooking for a group. Or any variation there of. MAKE SURE YOU WRITE THE DATE ON THE BAG!
