Pesto is one of those sauces that feels indulgent but can absolutely work in your favor when the ingredients are chosen thoughtfully. This version leans on walnuts instead of pine nuts, which is a smart swap — walnuts are rich in omega-3 fatty acids and have a deeper, earthier flavor that makes the finished sauce taste almost buttery. Nutritional yeast steps in for parmesan, delivering that savory, umami depth without any dairy, and it blends seamlessly with the bright basil and fresh lemon juice. Extra virgin olive oil ties everything together with healthy fats that support hormone balance, which is exactly what you want when managing PCOS through food. Toasting the walnuts first is a small step that pays off big — it coaxes out their natural oils and adds a warmth that makes the whole pesto taste more complex and restaurant-worthy. The food processor does the heavy lifting, so you're looking at a sauce that comes together in minutes with almost no cleanup. Toss it with pasta, spread it on grain bowls, or use it as a dip — it's the kind of versatile, feel-good recipe you'll keep coming back to.

Add the walnuts to a small dry skillet over medium heat and toast, stirring frequently, until fragrant and lightly golden, about 3–4 minutes. Watch closely, as they can brown quickly. Transfer to a plate and let cool for 2 minutes.
Combine the toasted walnuts, basil, nutritional yeast, garlic, lemon juice, salt, and black pepper in a food processor. Pulse 8–10 times until the mixture is coarsely chopped and roughly uniform.
