I'm a huge fan of Blue Apron. I have been using this service off and on for several years and have been consistently delighted with the quality, flavor, variety, and ease of making the meals they send.
I had gotten in the habit of taking my small family and eating out a lot, because I felt too busy to meal plan, or when I did, something came up and one of the things I'd purchased went to waste. It also seemed like I never had exactly the right consumable items (things like yogurt, ricotta, or lemon juice), or I had to buy produce in quantities that didn't work (like whole heads of cabbage when I only needed one quarter).
I did occasionally end up not making a Blue Apron meal because something came up, but a friend had suggested as a best practice to think ahead and throw the meat in the freezer (and even the "knick-knacks" depending on what was included) so nothing went to waste. Later, I could still make it after buying just a few dollars worth of produce.
Sometimes I choose not to get deliveries so I can buy ingredients myself and make meals that they've sent before, since I have the recipe cards and they even helpfully explain what is in things like seasoning mix or dressings they send.
I recommend Blue Apron for anyone who's interested in becoming a better cook, trying new menu items, feels like they don't have time to menu plan or shop, or wants ideas for how to change up what they already eat. It's also great for helping to get kids involved in cooking, in my experience. My daughter was a selective eater but from our first Blue Apron meal that we made together, she has been excited about their foods and open to trying almost everything they send.
