Since we met Henry and Ian from BOSH! at Vegan Camp Out in 2021, we’ve been huge fans, not only of their delicious plant-based meals but also their passion for the environment.

Here at Ecotricity, we’re proud to be the only vegan energy company certified by Viva! and The Vegan Society. So, working with Henry and Ian just made sense to us. Their commitment to putting more plants on plates to create tasty meals without a cost to the environment is one we can get behind. They’ve even introduced climate labelling on their recipes – showing their dedication to creating dishes which are better for our planet.

You may remember that this year we shared their Low Energy Cheeky Chow Mein recipe with you all – which was VERY delicious! You can find it here – if you missed out before. Now, Henry and Ian are back with their Roasted Cauliflower Fettuccine Alfredo recipe for us.

As the nights are starting to draw in, get your loved ones in the kitchen together to make this delicious dish. This is also the perfect recipe to try giving a plant-based meal a go! Trust us – you will not be disappointed.
