As someone who truly enjoys eating (and lovingly assembling each bite and taking my time, the social aspects, etc), I don't think I could fully move over to something like Soylent.
But during the weekday, I find thinking about lunch (packing it or deciding which restaurant to go to, etc) to be a real waste of time. In other words, are you guys exploring a formula that would work well for just "Monday to Friday lunches" combined with a regular diet for dinners and weekends?
