Boil chickpea pasta in salted water according to package directions until al dente, then drain.
Heat olive oil in a large skillet over medium heat and sauté diced chicken breast until golden brown and cooked through.
Add diced onion and minced garlic to the skillet, cooking for 3 minutes until softened and fragrant.
In a high-speed blender, combine soaked cashews, roasted red peppers, nutritional yeast, chicken broth, sea salt, black pepper, and smoked paprika.
