Bring a medium pot with water to a boil, season water with generous dash of salt (about 1-2 teaspoons). Cook pasta until "al dente" - it should have a bite to it and not be too soft.
In a high-powered blender, add tomato sauce, roasted peppers, cashews, water, red pepper flakes, and pinch of salt & pepper. Blend on high for 30 seconds or until consistency is super creamy and smooth. If sauce needs more flavor, add 1 garlic glove and season to taste with salt & black pepper if needed.
Warm red pepper sauce in pan over LOW heat. Then add cooked pasta to sauce with chopped basil. Serve and enjoy!
