Secondary school pupils in Torfaen can win an iPod Touch and £250 for their school by coming up with a catchy slogan for a healthy meals campaign.
Torfaen Council is asking pupils to think of slogans which could be used on bus adverts later this year.
Entries must be submitted by Sunday February 28. Two winners will then be chosen.
Secondary school pupils can email their ideas to Ben Payne, Torfaen Council, Panteg Way, New Inn, NP4 0LS or email ben.payne@torfaen.gov.uk.
A Torfaen Council spokesman said: "We want pupils to think of existing slogans like '5-a day' and 'you are what you eat' and come up with their own version."
The competition is part of the Appetite for Life project which has seen £200,000 spent on upgrading kitchens at seven comprehensive schools in Torfaen.
The project, which is funded by the Welsh Assembly, has also seen the introduction of a healthy meal action plan, aimed at giving schoolchildren a balanced and nutritious diet.
It has also provided better training for kitchen staff.
