Bring the water to a slight boil in a microwave glass dish or a stovetop pot. Remove the water from heat, add the cashews, and let them soak for 15 minutes.
Blend the cashews and water in a high-speed blender until completely smooth (cashew milk).
Cook the pasta according to package instructions. When done, drain and set aside.
Add the cashew milk, cheese, mustard, salt, and garlic powder to a large sauté pan on low to medium heat. Stir until the cheese is melted.
Mix the cooked pasta into the cheese sauce until well-coated.
Add more salt to taste.

Notes
-*Use 16 oz of pasta if you don't like it saucy.-You can get away with not soaking the cashews if you have a really good blender.-Block cheese melts better than pre-shredded cheese and doesn’t contain anti-caking ingredients.
