Preheat your oven to 375°F and lightly grease a small oven-safe baking dish.
Bring a large pot of salted water to a boil and cook the chickpea pasta for 2 minutes less than the package instructions suggest.
Add the finely chopped cauliflower florets to the boiling pasta water during the final 3 minutes of cooking time.
While the pasta cooks, sauté the diced chicken breast in a non-stick skillet over medium heat until golden and fully cooked through.
In a large mixing bowl, whisk together the Greek yogurt, nutritional yeast, Dijon mustard, garlic powder, onion powder, sea salt, black pepper, and smoked paprika until smooth.
Drain the pasta and cauliflower thoroughly, then immediately fold them into the yogurt sauce along with the cooked chicken.
Transfer the mixture into the prepared baking dish and sprinkle the parmesan cheese evenly over the top.
Bake for 12 to 15 minutes until the sauce is bubbly and the cheese creates a beautiful golden crust.
