What meals are you cooking for $3-4 on the Joule? Looking at getting a Joule soon.
Of course, those are average food prices in the US so YMMV. If you're in NYC or LA/SF, it's going to cost more than that no matter where you shop.
I mean, sous vide is amazing, but have you ever had your sprouts crispy? I used to be pretty indifferent to them until my fiancee cooked them up crispy.
Hmm... Now I'm thinking about food, oh look, its lunchtime.
