I don't see how it's any different than paying the premium for already diced, sliced or whatever
veggies available in the produce department and freezer section. There is a long wall of cooler with prepared produce in the store where I shop. You can buy just about anything already prepared for cooking. Usually, but not always there is quite a premium on the prepared items. Think about all the prepared and packaged items already available, those shaved down carrots called baby carrots, cole slaw and lettuces cut up in bags, sliced mushrooms, diced green peppers, onions, butternut squash. Brussels, cut up broccoli and so many other items. I think if I bought that kind of thing, I'd prefer getting them freshly cut rather than buy the bag that is who knows how old and may be treated with something to keep it looking fresh. And sometimes it's worth it for expediency.
