Real housewives Angela and Melinafrom Melbourne, VIC, food nerds Keiran and Nastassia from Perth, WA, and BFF's (Best Friends Forever) Ashlee and Sophia from Sydney, NSW. Of the lot, Ashlee and Sophia appeared the most fearsome with battle cries of, “We're going to kick them out of this competition one by one”, “We're hard arses and that's how we're going to bring it” and, about a rival's dish, “I don't understand it. Nor do I like it.”Next, the six teams travel to Melbourne for Angela and Melina's instant restaurant Bella Mamma.
