Bring a pot of salted water to a boil and cook the chickpea pasta until al dente, reserving 0.25 cup of the pasta water before draining.
While the pasta cooks, dice the pancetta and chicken breast into small, uniform pieces.
In a skillet over medium heat, sauté the pancetta and chicken until the pancetta is crisp and the chicken is fully cooked.
Add the minced garlic to the skillet and sauté for 30 seconds until fragrant, then remove the skillet from the heat source.
In a small mixing bowl, whisk together the whole egg, liquid egg whites, parmesan cheese, and black pepper until well combined.
Add the cooked pasta to the skillet with the meats, tossing to incorporate the residual heat.
Slowly pour the egg mixture into the skillet, stirring the pasta constantly to create a creamy, emulsified sauce without scrambling the eggs.
Add the reserved pasta water one tablespoon at a time if needed to achieve a silky consistency.
