Controversial highly processed meats such as chicken nuggets have been banned from all school dinners by the local council.
Landscove Primary children will tuck into farm-prepared food
The meats have recently been criticised by the celebrity chef Jamie Oliver for their high fat and salt content.
Devon County Council says this type of food will no longer appear on any of the menus at the 330 schools catered for by Devon Direct Services.
Children will now be offered home-made food, fresh fruit, salads and yoghurt.
Meanwhile, school children at a South Devon school will have their lunch cooked at a nearby farm from Monday.
Landscove Primary decided to opt out of Devon County school meals, and have food produced by Riverford Organic Farm instead.
About 90% of the fruit and vegetables will be organic and more than 60% of the meat will be local, and free range.
The price of lunch at the school is remaining the same at £1.50 per child and the number of children signing up for school dinners has risen from 20 to 80.
Guy Watson, the founder of Riverford, wants to prove good cheap school meals are possible.
He said: "My great dream is to demonstrate you can provide affordable meals from fresh ingredients, rather than pouring frozen food from cardboard boxes and debasing the whole experience."
In February a Devon school dinner lady resigned from a school near Plymouth.
Kate Steggles said she no longer wanted to be forced to serve processed meals to pupils at Newton Ferrers Primary School, saying the children "deserve better".
