ONE of My Kitchen Rules' most controversial teams was given the boot last night.

Melbourne's Thomas and Carla were the fourth team eliminated from the popular cooking show after suffering a complete kitchen meltdown.

The mates were easily beaten by Tasmanians Megan and Andy in the sudden death cook-off, in which the teams were asked to create dishes which showcased the key Queensland ingredients of Moreton Bay bugs, macadamia nuts and mangoes.

In the initial instant restaurant stage of the series, contestants are expected to score each other's dishes based on merit.

Thomas, a podiatrist, and Carla, a speech pathologist, earned the ire of many viewers and some of their fellow contestants after voting strategically to keep themselves in the competition.

Tonight, the remaining eight teams are asked to prepare a seafood banquet.
