Bring a pot of salted water to a boil and cook the chickpea pasta according to package directions until al dente, reserving 0.25 cup of pasta water.
While pasta cooks, dice the chicken breast into bite-sized pieces and season with sea salt.
In a large skillet over medium heat, cook the pancetta until crispy, then remove and set aside on a paper towel.
In the same skillet using the rendered fat, sauté the chicken and minced garlic until the chicken is golden and cooked through.
In a small bowl, whisk the egg and parmesan cheese together until smooth.
Lower the skillet heat to low, add the cooked pasta and fresh spinach, tossing until the spinach begins to wilt.
Remove the skillet from heat entirely and quickly stir in the egg mixture and reserved pasta water, tossing constantly to create a silky, creamy sauce without scrambling the eggs.
Stir the crispy pancetta back in and finish with a generous amount of freshly cracked black pepper before serving.
