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, heat a large non-stick skillet over medium-high heat and add one tablespoon of the vegetable broth.
Add the cubed chicken breast to the skillet and season with half of the sea salt and black pepper, sautéing until the chicken is cooked through and golden brown.
Remove the chicken from the pan and set aside, then add the remaining tablespoon of vegetable broth to the same skillet.
Add the sliced cremini mushrooms and minced shallots to the skillet, sautéing until the mushrooms have released their moisture and turned tender.
Stir in the minced garlic and cook for an additional 30 seconds until aromatic.
Drain the pasta, reserving two tablespoons of the cooking water, and add the pasta and cooked chicken back into the skillet with the mushrooms.
Remove the skillet from the heat and drizzle the truffle oil over the mixture, tossing everything together with the reserved pasta water to create a light, cohesive sauce.
Garnish the dish with fresh chopped parsley and the remaining sea salt and black pepper before serving immediately.
