You get delivered e.g 5 meals day before, evening for next day

Healthly food, calculated calories, good stuff in general.

When you are living alone then it is really good option because when I calculated my shopping costs then switching to it wasnt more expensive and im eating way better while saving time

I'm guessing those Meals in Boxes as a Service you can subscribe to, where they drop a bunch of calorically deficient, bland, starvation-level meal packs at your doorstep in the middle of the night, and you're supposed to survive on them for the next 24 hours.
