I love roasting because you can give it love, get it in the oven and go and play with the kids or whatever you've got to do, and then hours later you've got a lovely dinner.

I think authenticity is important whichever homeland you're from but one of the lovely things about British cooking is that we adopt great food and dishes from all of the lovely people who come from overseas to live in our country. We're a magpie nation - we take the best bits of other cuisines and embrace them as our own.

Every kid in every school no matter their background, deserves to learn the basics about food - where it comes from, how to cook it and how it affects their bodies. These life skills are as important as reading and writing, but they've been lost over the past few generations. We need to bring them back and bring up our kids to be streetwise about food.

Heads know that failing to invest in good, nutritious food is a false economy and parents won't tolerate reconstituted turkey being put back on the menu.

The public health of five million children should not be left to luck or chance.

As usual, my timing is bizarrely good.

I challenge you, to go to any school and open 50 lunchboxes, and I guarantee you there will be one or two cans of Red Bull, there'll be cold McDonald's and jam sandwiches with several cakes.
