The last of the ingredients provided to me by the lovely folks at buywholefoodsonline.co.uk was Vital Wheat Gluten, which has many uses from bread and cakes to, one of the more popular applications of late, Seitan, a meat replacement product.
I had heard about the meat like qualities you could get by combining Vital Wheat Gluten with lentils, spices and other flavourings.
Start by adding your Vital Wheat Gluten, lentils (I used precooked tinned green lentils), water, nutritional yeast, tomato purée, soy sauce (I used dark because it is more flavourful), garlic, chilli powder and black pepper to a food processor.
The Vital Wheat Gluten had formed strands like you get in meat.
