The Norwich owners of a vegan pizza company challenge national treasure Mary Berry to go plant-based on the next episode of her new TV series.

Father and son duo Mike and Joe Hill founded One Planet Pizza in 2016 and it was the UK's first frozen pizza brand.

Five years later and after a Crowdfunder gained investors from all over Europe, it is now in more than 500 independent shops across the UK and their production unit is based in Hethersett.

The pair will appear on Thursday night's episode (November 18) of Mary Berry - Love To Cook on BBC2 at 8pm.

They whip up a vegan feast for the celebrity chef and food writer, with barbecue pulled jackfruit and turmeric tofu scramble and it was filmed in Oxfordshire.

Joe Hill, 30, said: "Mary was as lovely as you would imagine and she was genuinely interested in learning about new foods.

"We are very excited for the show and I hope it helps gets our vegan pizzas in front of new people."
