My experience from trying it out a few years ago is that you do all the work. Nothing comes prepared, so basically a box of ingredients + the recipe. I would think it would be a good way to learn how to cook. I hated this, and would rather have all the prep work done for me (e.g. diced onions instead of a whole raw onion). Also I didn't like all the packaging/ice packs/bubble wrap. It all seemed really wasteful compared vs. going to the store with reusable bags.
That being said, the food/recipes were good but the portions were pretty small for two people. I think this would have been perfect when I was single and had a lot more time on my hands.
Recently they’ve been moving towards preprepped or semi prepped ingredients such as presliced beef and chicken, prechopped kale. Not sure if that’s a pro or a con, but it does make the recipes faster to prepare
