Hare Krishna devotee Buddhi Wilcox ran a vegetarian cafe in Auckland's Queen St in the 1990s.
Now he cooks hot vegetarian lunches for 1000 children a week through his Food for Life in Schools programme in Northland.
The programme is growing rapidly, with more than 70,000 meals served since he started two years ago.
"The challenge is to provide a meal which is tasty, has nutritional value, is practical to cook in bulk and is cost-effective."
Dishes like vegetarian shepherd's pie, lentils, pasta, banana fritters, apple crumble and rice pudding are served once a week to children at five schools. The schools pay $1 a meal.
