Her Instagram feed is packed full of inspiration."Christian Stevenson @djbbq"He's got the best energy, cooks amazing BBQ and is always smoking meat somewhere in the world. He's mad, fun, passionate and crazy."Chris Bianco @pizzariabianco"Simply the best pizzas and an amazing human being so in tune with his cooking, his staff, his customers, the seasons and the farmers. He always teaches me something."David Loftus @davidloftus"I've been shooting with him for 17 years now.
