Bring a pot of water to a boil and cook orzo according to package directions. Once cooked, drain and set aside.
Start by soaking the cashews in boiling water and let sit for about 5 minutes. Finely dice your broccoli florets and set aside.
In a blender, blend soaked cashews, vegetable broth, lemon juice, nutritional yeast, raw garlic, olive oil, miso and salt. Blend until smooth, adjusting to taste as needed.
In a saucepan, add a touch of neutral oil and the broccoli florets. Cook for a few minutes, stirring with a spatula, until bright green and tender. If you prefer it softer, add a splash of water to "steam" the broccoli further. Add the sauce to the pan along with the cooked orzo. Stir to combine.
When ready to serve, top with vegan parmesan if desired and black pepper, to taste.
