McDouble is 'cheapest and most nutritious food in human history' - Telegraph:

The double cheeseburger provides 390 calories, 23 grams of protein – half a daily serving – seven per cent of daily fibre, 19 grams of fat and 20 per cent of daily calcium, all for between $1 and $2, or 65p and £1.30, The Times reported.
Kyle Smith, a New York Post columnist, threw his support behind the McDouble’s nutritional value for money.

“Facts are facts – where else but McDonald’s can poor people obtain so many calories per dollar?”
Mr Dubner added: “The more I thought about the question, whether the McDouble is the cheapest, most bountiful, and nutritious food ever, the more I realised how you answer that question says a lot about how you see the world, not only our food system and the economics of it, but even social justice...”
