Thai food is on the menu so Diana enlists the help of mentor and Thai food enthusiast, Gary Mehigan, who is an expert at striking the balance of salty, sweet and sour.

Inspired by the diverse cultures of Singaporean street food, Diana cooks one of her favourite hawker style dishes, hokkien mee, a simple noodle dish created using homemade prawn stock.

Korean food is fast becoming a staple cuisine in Australia, particularly fried chicken and Korean BBQ - but there is so much more to explore.

Diana then makes a vegetarian version of bibimbap - a versatile and wholesome mixed rice dish full of vibrant flavours.
