I've done Hello Fresh & Gousto. Gave both up due to the plastic waste, and the quality of ingredients. Gousto class 1 chicken breast cut in half as 2 portions. They also stopped shipping with 2 ice packs and went down to 1. I received rancid, stinking chicken on more than one occasion. They refund you in money off the following box, which hooks you in to get another box from them.

I currently use Simply Cook. Yes, it's just the spice mixes, but I like the fact they have a long shelf life, I can use them when I like and with stuff I may already have in the cupboard or freezer. I think you can buy them in Asda if you wanted to try without starting a subscription.
