Marmite pasta made famous by Nigella. I basically followed Nigella's recipe but with the vegan substitute. I ignored the cheese as I had no vegan cheese. I tried it and enjoyed it as a fairly plain meal. Just pasta, vegan margarine, marmite and peas. I thought it was almost as easy as my love of Sainsbury's Vegetable noodles but plainer.
Sometimes I feel like really plain (but salty) food but I might add ketchup next time, as this recipe on the Guardian website suggests.
