I see a lot of anger in the comments, some of them questioning the practicality of it or the actual approach you'd use if money was an issue in your household.

The BBC didn't do this in order to educate people on how to eat cheap. This is just a flashy piece intended to provoke the "oh look how easy is to make something cheap look nice and healthy" reaction.

In that sense its similar to the "deconstructed McDonalds meals" by famous chefs or the "how to substitute x by y and make your children eat y" ones. No one who has to leave on £1 a day will look here for practical advice and discussing the practicality of it is, therefore, pointless.
