Wash mushrooms thoroughly and cut into long thin slices. Heat a pan, add remaining oil and fry on a medium heat. Simultaneously, boil water in a pot, add salt and then pasta (you can use any type of pasta), cook it for as long as instructed on its packaging. Drain it when ready, add to fried mushrooms in the pan and pour some soymilk. Add a preferred amount of pesto and after two minutes, move it on a plate.
