Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper.
Slice the carrots into thin rounds and cut the red onion into 1-inch wedges.
Place the Quorn pieces, carrots, onion, and cherry tomatoes onto the prepared baking sheet.
Drizzle with olive oil and season with sea salt, black pepper, and dried oregano, tossing well to ensure every piece is coated.
Roast for 20 to 25 minutes, or until the vegetables are tender and the Quorn pieces are lightly browned and caramelized.
While the vegetables roast, cook the chickpea penne in a pot of boiling salted water according to the package instructions, then drain and reserve 2 tablespoons of the pasta water.
In a large mixing bowl, combine the roasted Quorn and vegetable mixture with the cooked pasta and minced garlic.
Sprinkle in the nutritional yeast and parmesan cheese, adding the reserved pasta water to help create a light, savory sauce.
Toss everything together until well combined, garnish with freshly chopped parsley, and serve immediately.
