Reconstitute the TVP by adding the yeast extract to 1 cup boiling water, allowing it to sit for 15 minutes and then adding the other cup of boiling water, stir, let sit for another 15 mins and drain.
Fry the onions, leek, and garlic in the oil until just translucent. Add the carrots, mushrooms, tomato paste, stock cube, salt, pepper, herbs, a little red wine, soy sauce, and water so nothing sticks. Put the lid on, and allow to cook over medium heat for about 15-20 minutes, stirring frequently.
In the meantime, boil the potatoes in salted water for about 15
