Jamie Oliver may have done a great deal for school meals but he's made searching for 'school dinners', on Google, an absolute nightmare! Here are a few things I've found:

If you can locate the 'Register' button on that site (it's in the 2nd box up above the first post), you can register for free. You'll then be able to send a message to Queenie (click on her username) who has offered to supply lots of recipes. (See the 3rd post down).
