Bring a large pot of salted water to a boil and cook the chickpea pasta according to package instructions until al dente.
While the pasta cooks, place the pancetta in a cold skillet and turn the heat to medium, sautéing until the fat renders and the meat becomes crispy.
In a small mixing bowl, whisk together the whole egg, liquid egg whites, and grated parmesan cheese until the mixture is smooth.
Reserve approximately 0.25 cup of the starchy pasta cooking water before draining the noodles.
Turn off the heat under the skillet containing the pancetta and add the hot, drained pasta directly to the pan.
Slowly pour the egg and cheese mixture over the pasta while tossing constantly with tongs to create a creamy emulsion without scrambling the eggs.
Gradually add the reserved pasta water one tablespoon at a time if needed to reach a glossy, silk-like sauce consistency.
Season the dish with fresh black pepper and sea salt, then garnish with chopped fresh parsley before serving immediately serving.
