Bring a large pot of salted water to a boil and cook the chickpea pasta until al dente, reserving 1/4 cup of pasta water before draining.
While the pasta cooks, add the diced pancetta to a cold skillet and turn the heat to medium, cooking until the fat renders and the meat is golden and crispy.
In a small bowl, whisk together the whole eggs, liquid egg whites, and grated parmesan cheese until the mixture is well combined and smooth.
Add the minced garlic and fresh spinach to the skillet with the pancetta, sautéing for 1 minute until the spinach is just wilted.
Reduce the skillet heat to low, add the cooked pasta, and slowly pour in the egg mixture while stirring constantly to create a creamy, emulsified sauce.
If the sauce is too thick, add the reserved pasta water one tablespoon at a time until the desired silky consistency is reached.
Season with sea salt and plenty of freshly cracked black pepper before serving immediately.
