We have Green Chef which I saw recommended on here. I really like it, the recipes are good and there is also a range of e.g. keto, and low carb recipes.
They do an offer where the first box (for 3 meals for 2) is free I have a code is anyone is interested, along with £10 off the next 3 boxes.
You can also refer people and it gives you £15 off your next order.
I didn't think we would continue with it but we liked it so much we have.
We just intended to have the free box.
I think they may be owned by Simply Cook as some of the ingredients have this written on them.
They do good portions and the fish and prawns are really good sizes and quality. (we don't eat chicken or red meat so can't comment there)
You can just state your food preference (for example we are pescetarian) and it will send you e.g. 3 meals every week.
Ours arrives on a Saturday morning which I find convenient and it is packaged well, not too much waste.
I like how the meals are numbered and places in brown paper bags, with the refrigerated stuff packed seperately in ice, ready to stick in the fridge.
I have learned new ways of cooking from it, and have kept some of the recipes to cook myself in future.
