Cook the gluten free pasta according to package directions. Drain and set aside.
In a skillet, heat olive oil over medium heat. Cook chicken slices until golden and fully cooked, about 6-8 minutes. Remove and set aside.
In the same skillet, sauté garlic until fragrant, about 1 minute.
Blend soaked cashews, almond milk, nutritional yeast, lemon juice, garlic, salt, and pepper until smooth.
Pour the sauce back into the skillet, bring to a gentle simmer, then add chicken.
Toss in the cooked pasta, stirring until evenly coated.
Serve hot, topped with fresh parsley.
