Bring a large pot of salted water to a boil and cook the chickpea spaghetti according to package directions until al dente.
Reserve 0.25 cup of the starchy pasta water before draining the noodles.
While the pasta cooks, place the diced pancetta in a large skillet over medium heat and sauté until the fat has rendered and the meat is crispy.
In a small mixing bowl, whisk together the whole egg, egg yolks, liquid egg whites, and grated parmesan cheese until smooth.
Add the baby spinach to the skillet with the pancetta and stir for 1 minute until just beginning to wilt.
Turn the heat to low and add the cooked spaghetti to the skillet, tossing to coat in the pancetta drippings.
Slowly pour the egg mixture into the skillet while constantly stirring the pasta to prevent the eggs from scrambling, creating a creamy emulsion.
Add the reserved pasta water one tablespoon at a time if needed to reach your desired sauce consistency.
Season with sea salt and a generous amount of freshly cracked black pepper before serving immediately.
