Soak the cashew nuts in warm water for 20 minutes, rinse them, then put them in the blender and cover lightly with water. Mix until you get a creamy consistency. Add enough water until it is nice and milky, but not too thin! Add Himalayan salt and pepper.
Finely chop 2 medium-sized onions, fry in a little olive oil, deglaze with a little water. Finely chop approx. 200g brown mushrooms, add, finely chop a small zucchini, add. Add cashew sauce, bring to the boil briefly. Danger! The cashew sauce thickens by itself! Pay attention to the consistency, if necessary slowly stir in a little water. Season with a little garlic, salt and pepper to taste.
In the meantime, cook the pasta and serve everything together.
