The Feed Me Vegan meals, which include shepherds pie, spicy chili, and curry, were put on shelves in 155 Waitrose & Partners stores across the country last October.
Now, thanks to growing demand, they are also available from Ocado - the world's largest dedicated online grocery retailer.

The meals, which are all gluten-free, nut-free, under 500-calories, and made in a vegan factory, are sold in plastic-free packaging. The outer box is recyclable and the tray is biodegradable.
"Over the past few years I have been working hard to pave the way in making veganism accessible for everyone through creating vegan meals which are easy, healthy and delicious whilst ensuring all food packaging is sustainable for the good of the planet and to set the standard in the future of food," Watson exclusively told Plant Based News.
"Launching with Ocado today is so important to me as we are becoming more accessible through two of the biggest food retailers (Ocado and Waitrose & Partners) which means more people can access good quality, fuss free, vegan food."
