We were gifted a free week of Blue Apron by friends as well. I think it's made for people who 1) have a lot of money but not a lot of time, 2) like to cook but don't like to plan meals, 3) like a lot of variety in their meals, and 4) like meals that are really gourmet using all fresh ingredients. If you need two carrots for meal #1 and 3 sprigs of cilantro for meal #2 and a quarter-head of cabbage for meal #3, and really want everything to be fresh, and you don't want to plan your meals so you do ALL cabbage meals or ALL carrot meals that week because you want the variety, well, it can be hard to do that without wasting ingredients unless you use something like Blue Apron.
This is basically the exact opposite of how I cook. I didn't like it because I spent 35-45 mins 3x in the week and got 6 meals out of it (ok, maybe closer to 8-9, as the portions are on the large side), whereas normally, I might cook 2-3 times per week for 20-30 mins, but cook enough to serve 8, so that we have plenty of leftovers for lunches and other dinners. Add another 30 mins for the meal planning & weekly grocery shopping, and I'm spending the same amount of time, but getting way more meals. But as a result I only cook things that re-heat well, and I tend to do things like use frozen peas instead of shelling fresh peas myself, as one of the Blue Apron recipes had me do. And, of course, I'll eat the same meal multiple times in a week. But I've never been known for my gourmet palate, so it works for me. I did like getting to try the new recipes though, and at least one of them I'd simplify a bit and make again.
