Puree the pesto ingredients in a blender to a smooth mass. If the mixture is too thick, gradually add a little more soy milk. The pesto should be liquid at the end, but not too thin.
Heat some vegetable oil in a large pan. Fry the mushrooms, season with salt and pepper. As soon as the mushroom water has boiled down, add the gnocchi and fry for another 5 minutes. Divide the rocket, mushrooms and gnocchi on 2 bowls. Add the pesto and stir in.
