Hundreds of students at Saint Catherine's School in Halifax are enjoying a free lunch made by their schoolmates in honour of World Food Day.

Earlier this week, Grade 5 students at the school on Connolly Street picked the remaining food from the school garden and made a potato soup with the help of professional chefs from the Brooklyn Warehouse, a local restaurant.

"It's fun just getting muddy and looking for stuff," said Jennifer McGuire, one of the Grade 5 students helping to harvest potatoes, tomotoes, onions and cucumbers.

Deirdre Evans, one of the parent volunteers that help make the Saint Catherine's School garden grow, said it's a learning experience for the children.

"This is about making the connection between what kids see on their plates, and the food, where it comes from. Healthy eating," she said.

Each of the 411 students were set to enjoy potato soup and a roll.

"It's great to show them how to do it and they want to master the skill," Gray said Monday.

"To be able to show them the end result of the soup that they created will be great."

World Food Day was proclaimed in 1981 by the Conference of the Food and Agriculture Organization to mark the founding of the organization in 1945.

The aim of the Day is to heighten public awareness of the world food problem and strengthen solidarity in the struggle against hunger, malnutrition and poverty.
