Bring a large pot of salted water to a boil and cook the chickpea pasta according to package instructions until al dente.
While the pasta cooks, dice the chicken breast into bite-sized pieces and season with sea salt and black pepper.
Heat the olive oil in a large skillet over medium-high heat and sear the chicken until golden brown and cooked through, then remove from the pan and set aside.
In the same skillet, add the sliced cremini mushrooms and minced shallots, sautéing until the mushrooms are tender and browned.
Add the minced garlic to the skillet and cook for 30 seconds until fragrant.
Pour in the chicken bone broth and stir in the nutritional yeast, allowing the liquid to simmer and slightly thicken into a light sauce.
Return the cooked chicken and the drained pasta to the skillet, tossing everything together to coat thoroughly in the sauce.
Remove the pan from the heat and drizzle with the truffle oil, then garnish with chopped fresh parsley before serving.
