Wouldn't recommend Hello Fresh at all. Used their service as they had a black friday deal for £16 which worked out cheaper than my weekly shopping but they forgot to pack a meal and gave me the wrong ingredients for a different meal. The options for vegetarians is also pretty limited and for vegans it's basically non-existent. If you try and cancel you have to go through 4 or 5 cancellation screens. They try and ask you if you have special dietary requirements like vegan, at which point they re-direct you to their other company which is Green Chef. I'd avoid that too although I've heard it is better.
The fruit and veg was also pretty old looking by the time I got mid way through the week. The food I did cook was very tasty but I struggle to see how any of the ingredients or quality of the menus are worth full price? They were quick to give me a refund but defaulted it to Hello Fresh website credit. I asked for it to be sent to my bank account straight away instead and they agreed.
Do yourselves all a favour, find some of their recipes (or anyone elses) and buy the ingredients yourself! Shop local too!
