Tesco claims it is making supermarket salad history by becoming the first retailer to add organic pea shoots to its range of washed and ready-to-eat bagged salads.

They are being marketed as an excellent source of the antioxidants vitamin A and vitamin C.

Organic salad buyer Emma Pettitt said she hoped it would help Tesco boost sales in the category, which are already up 40% year-on-year. "We believe our shoppers will increasingly look to organic food for genuine newness," she said.

The new product is supplied by Vitacress and will be launched at the beginning of next month in a 50g pack retailing at £1.29.
