We had homemade pizza with premade bases from the fridge and various toppings plus salad, £1.50 per head. Then yoghurt for pudding which will add another 50p or so each.
Have just worked out that per month a family of four would eat 360 meals for one in a 30 day month (3 meals a day times 4 people times 30 days)
So £1 average per person a meal = £360/month
£2 average per person a meal = £720/a month
£3 average per person a month = over £1K!!!
