Monica Galetti: ‘My goal was to be a chef, it wasn’t to be on TV’

The chef on 13 years of MasterChef: The Professionals, the many uses of Marmite and why she can't have a banana in peace

I grew up in Samoa and, looking back, I don't think I realised how wonderful life was back then. The chickens used to run wild on the family plantation and we'd collect their eggs. We'd pick guavas, pineapples, papayas. It was such a normal thing to do.

Every Sunday, we'd have an umu" - a big fire pit with volcanic rocks. When the fire dies down, the rocks are taken off and you lay it with the meat or palusami [wrapped bundles of taro leaves with a coconut and onion filling]. Then it all gets topped with the rocks and covered with banana leaves and left for an hour to cook. The whole family get involved, everyone had a role.
