Let the cashews soak overnight or scalded with boiling water for 15 minutes.
Cook the pasta in salted water as usual.
Put the lemon zest in a bowl in which the pasta will be mixed with the sauce later.
Put cashews, soy yogurt, water, apple cider vinegar, salt, lemon juice in a powerful blender. Blend until the sauce has a creamy consistency (take breaks if necessary). This may take several minutes.
Mix the cooked, hot noodles in the bowl with the lemon zest together with the sauce. Season with more lemon juice and salt if necessary.
Sprinkle with a little pepper and enjoy!
