Cook pasta according to package instructions. Drain and drizzle with olive oil to prevent sticking.
Heat olive oil in a skillet over medium heat.
Add minced garlic and sauté until fragrant and lightly golden.
Toss in vegan shrimp and cook for 3–4 minutes until slightly crisp.
Add spinach and sauté until just wilted.
In a blender, combine soaked cashews, almond milk, nutritional yeast, lemon juice, salt, garlic powder, and onion powder.
Blend until smooth and creamy.
Pour the sauce into the skillet with the shrimp and spinach.
Add the cooked pasta and toss until evenly coated.
Adjust salt and pepper to taste, then serve warm with parsley and chili flakes.
