- 1 cup unroasted cashews
 - 1 cup vegetable broth
 - 3 tablespoons nutritional yeast flakes
 - 3 tablespoons fresh lemon juice
 - 2 teaspoons white miso
 - 2 teaspoons onion powder
 - 1/2 teaspoon salt, or to taste
 - black pepper to taste
 - 8 ounces small shell pasta or macaroni
 - 1 1/2 cups arugula (optional)
 
- Blend cashews, broth, yeast, lemon juice, miso, and onion powder in a high-powered blender (such as a Vitamix(R)), scraping down sides with a spatula until completely smooth. Season with salt and pepper, keeping in mind that you want it just a little saltier than usual because it's going to be poured over other ingredients.
 - Meanwhile, bring a pot of salted water to a boil and cook pasta according to package directions.
 - Drain, return to pot, and stir in cashew sauce. Cook over low heat, stirring, until sauce thickens a bit and everything is deliciously creamy, about 3 minutes. Stir in arugula (if using) and add more salt, if needed. Serve immediately.
