Bring a large pot of salted water to a boil and cook the chickpea pasta according to package directions until al dente.
While the pasta cooks, season the sliced chicken breast with the sea salt and black pepper.
Heat a large non-stick skillet over medium-high heat and sear the chicken until golden and cooked through, then remove the chicken from the pan and set aside.
In the same skillet, add the sliced cremini mushrooms and sauté until they release their moisture and become deeply browned.
Stir in the minced shallot and garlic, cooking for about 1 minute until the aromatics are fragrant.
Pour in the chicken bone broth to deglaze the pan, scraping up any browned bits from the bottom to create a light sauce.
Add the cooked pasta and seared chicken back into the skillet, tossing everything together to coat in the pan sauce.
Remove the skillet from the heat and drizzle with the truffle oil, then sprinkle with grated parmesan cheese and fresh parsley before serving.
