Zambrero is an Australian multinational fast food restaurant franchise serving Mexican cuisine.

It was founded in Canberra by then-medical student Sam Prince with the idea of using the profits to support humanitarian causes.

[1][2] Zambrero is one of Australia’s largest Mexican food franchise with over 300 restaurants globally.

[13][14][15] The company had shifted from an earlier goal of supplying educational resources to indigenous communities and developing countries, for which Prince had founded the E-magine Foundation in 2007, to reducing global hunger.

[19] A 2016 study by the George Institute for Global Health, analysing 229 small meals and snacks from 25 fast food chains, found Zambrero's pork nachos to have the highest kilojoule count.
