Cook the pasta as per pack instructions, drain and keep some of the water in a bowl.
Wrap the onion and the garlic in foil paper and bake for 20 minutes or until the onion is nice and soft. Then place all the ingredients in a food processor, except the pasta and the chopped thyme, and blend until a smooth consistency, tasting for seasoning. Combine the mixture with the pasta, add the thyme and combine well. Place the mixture in a baking dish, sprinkle with breadcrumbs and some vegan cheese.
Bake for 15 minutes.
