The feeling for that vegan Wellington is naturally gluten-free as long as you swap out the vegan breadcrumbs for a gluten-free alternative. In some countries you can also get vegan-friendly gluten-free puff pastry from the fridge aisle of the supermarket, so if your local grocery store stocks gluten-free vegan puff pastry, then yay! In this case, it is a simple swap. For the base recipe, all you need is two sheets of puff pastry, thank you are good to go!
