Cook 10 ounces chopped white mushrooms in olive oil in a large nonstick skillet over medium-high heat until golden, 8 to 10 minutes, stirring halfway through. Stir in 1 teaspoon soy sauce, 2 grated garlic cloves and 1/2 teaspoon lemon zest; transfer to a bowl. Add 1 tablespoon olive oil and a 12-ounce package refrigerated gnocchi to the skillet. Cook, stirring, until crisp, 5 minutes. Stir in the mushrooms and 1/4 cup chopped parsley. Season with salt and pepper.
