Bring a pot of salted water to a boil and cook the chickpea pasta according to package directions until al dente, reserving a small amount of pasta water before draining.
While the pasta cooks, heat the extra virgin olive oil in a large skillet over medium-high heat and season the diced chicken breast with sea salt and black pepper.
Add the chicken to the skillet and sauté for 5-6 minutes until golden brown and cooked through, then remove the chicken from the pan and set aside.
In the same skillet, add the sliced cremini mushrooms and sauté for 4-5 minutes until they release their moisture and turn a deep golden brown.
Add the minced garlic to the mushrooms and cook for 1 minute until fragrant, then stir in the baby spinach and cook just until wilted.
Reduce the heat to low, then return the chicken to the skillet and add the cooked pasta, Greek yogurt, grated parmesan, and a splash of the reserved pasta water.
Toss everything together until a creamy sauce forms and coats the pasta evenly, ensuring the heat remains low to prevent the yogurt from curdling.
Remove from heat, drizzle with the truffle oil, and garnish with fresh parsley before serving.
