Bring a pot of water to a boil and cook the chickpea pasta according to package directions until al dente.
While the pasta cooks, dice the chicken breast and pancetta into small, uniform pieces.
In a large skillet over medium heat, cook the pancetta until the fat renders and it becomes crispy.
Add the diced chicken and minced garlic to the skillet, sautéing until the chicken is golden and cooked through.
In a small bowl, whisk the whole egg and grated parmesan cheese together until smooth.
Reserve 2 tablespoons of the pasta cooking water, then drain the pasta and add it to the skillet with the chicken and pancetta.
Turn off the heat and immediately stir in the fresh spinach until it begins to wilt from the residual heat.
Quickly pour in the egg mixture and reserved pasta water, tossing constantly to create a creamy sauce without scrambling the eggs.
Season with sea salt and black pepper before serving immediately in a warm bowl.
