Cook pasta as per packet directions. Gluten-free pasta usually cooks in around eight minutes (for al dente).
Add basil, nutritional yeast, spinach, pine nuts, cashews, garlic granules, olive oil and salt to a food processor and blend until combined. Adjust seasonings to taste then mix the pesto through the cooked pasta, spoonfuls at a time.
Once you have reached your desired pesto to pasta ratio, add the cherry tomatoes then serve.
Any leftover pesto can be stored in the fridge, but let it sit at room temperature before eating as the oil may solidify from being refrigerated.
