Cook pasta until al dente. Drain and toss in 1 tablespoon of olive oil to keep from sticking.
Heat 2 tbsp olive oil in a large skillet over low-medium heat. Add the garlic, onion and squash. Cook for ~10 minutes, stirring occasionally until the squash is penetrable with a fork.
Add the veggies to a blender with rice milk, cashews and spices. Blend until creamy.
Add the sauce back to the skillet and sauté for about 5 minutes, stirring often, to warm. Stir in the cooked pasta. Serve topped with vegan parmesan.
Notes
*Soak cashews for 2 hours before using to ensure a creamy texture.
