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 boils, sauté the diced pancetta in a large skillet over medium heat until golden and crispy.
Add the minced garlic to the skillet with the pancetta and cook for 1 minute until fragrant, then reduce the heat to low.
In a small bowl, whisk together the whole egg, egg whites, and grated parmesan cheese until the mixture is smooth.
Reserve 0.25 cup of the pasta cooking water, then drain the pasta and add it immediately to the skillet with the pancetta.
Remove the skillet from the heat and slowly pour in the egg mixture while tossing the pasta constantly to create a velvety sauce.
Thin the sauce with the reserved pasta water as needed, then season with black pepper and sea salt and garnish with fresh parsley.
