Bring a large pot of salted water to a boil and cook the chickpea linguine according to package directions until al dente.
Reserve 1/4 cup of the pasta cooking water before draining the noodles.
Season the chicken breast with half of the sea salt and black pepper.
Heat the olive oil in a large skillet over medium-high heat and sear the chicken for 5-6 minutes per side until fully cooked, then slice into thin strips.
In the same skillet, add the minced shallots and sliced cremini mushrooms, sautéing for 5 minutes until the mushrooms are browned and tender.
Stir in the minced garlic and cook for 30 seconds until fragrant.
Pour in the chicken bone broth to deglaze the skillet, using a wooden spoon to scrape up any flavorful browned bits from the bottom.
Add the cooked linguine, sliced chicken, and reserved pasta water to the skillet, tossing constantly to create a light sauce.
Remove from heat and drizzle with truffle oil, then sprinkle with parmesan cheese, fresh parsley, and the remaining salt and pepper.
Toss one final time to ensure the pasta is evenly coated and serve immediately.
