We have this where I live overseas. I pay £70 a month and every week day get a delivery of two meat/fish/tofu dishes and one vegetable dish. I cook whatever carbs I fancy (usually rice) and just heat up the meat and veg in the microwave or oven and dinner is done. No planning what to eat, shopping, cooking or food waste and very little clearing up.
I wish we had something like this in the UK, I'll really miss it when we move back home! I was looking for something similar but can only find frozen ready meals which aren't really the same. I guess meal prepping is the closest.
No point to this post really, just wanted to share what a great idea I think it is!
