What toaster oven do you use? We've put ours away because it hasn't been that great.
We've got a Breville. It's the most valuable cooking appliance in the house: it gets up to 500f very quickly and holds a much more consistent temperature than our pro-grade oven, and the built in timer makes most things fire and forget. I don't think I'd trade the oven for another Breville toaster oven, but if I could get 2 more in exchange for the oven I'd have to think carefully about it.
If you wanted to be super pedantic about it, you'd say that none of this is anything like "sous vide" because "sous vide" implies "under a vacuum".
At any rate: dishwasher salmon and sous vide salmon are, literally, the same dish.
