Preheat your oven to 375°F (190°C).
Cook the chickpea pasta in boiling water for 2 minutes less than the package instructions to keep it firm, then drain and set aside.
Steam the cauliflower florets until they are very soft, then transfer them to a blender or food processor.
Add the Greek yogurt, nutritional yeast, and Dijon mustard to the blender and process until the mixture is completely smooth and creamy.
In a non-stick skillet over medium heat, cook the ground turkey until browned and no longer pink, breaking it into small crumbles.
Season the turkey with garlic powder, onion powder, sea salt, and black pepper.
In a large bowl, combine the cooked pasta, browned turkey, and the creamy cauliflower sauce.
Fold in half of the shredded cheddar cheese until well incorporated.
Transfer the mixture into a small oven-safe baking dish and sprinkle the remaining cheddar cheese over the top.
Bake for 12-15 minutes until the cheese is melted and the edges are slightly golden.
