Family food budget?

After a trip to Tescos and an additional £32 spent I am wondering what budget we should be aiming for?

The reality is I have no idea what we should spend, with all the recent food price increases I don't know what is reasonable - how much would you say to feed a family of 6 healthily for 1 week?

I know a budget would normally be 'what you can afford' however, I want a challenge to see how well we can do. I am finding it fun thinking of simple, cheap and healthy meals. 



A great example is yesterdays budget lunch, pasta in a tomato sauce. It was Giz's creation! He boiled up the pasta and added tinned tomatoes, garlic, herbs and a little salt and pepper. (He has good taste buds!) We had a slither of cheese in the fridge and he grated this in, stirred it up and served. It was delicious and a big hit with the all the children. I didn't work it out but I'm sure if I had it would have been pence per portion. 

This week so far I have spent just over £50. I have worked out our meals and we wont need to buy any more food until Saturday. So, £50 for the whole week - I would say that was a success, it works out at £7.14 per day to feed 6, which is just over £1 per person per day.

To be honest, we do already have quite a bit in the cupboards -  there is plenty of cereal for breaky and we still have gammon from Christmas (we are having it for tea tonight). I wonder if we can keep it up, £50.00 per week or £200 per month to feed us 6 healthily. Lets see.....

Please comment and let me your thoughts or perhaps what your budget is.
