Bring a large pot of salted water to a boil and cook the chickpea pasta according to package directions until al dente.
While the pasta cooks, heat a large skillet over medium heat and add the pancetta, sautéing until it becomes golden and crispy.
In a small bowl, whisk together the whole egg, egg whites, grated parmesan cheese, and black pepper until well combined.
Add the minced garlic and frozen peas to the skillet with the pancetta, cooking for 1-2 minutes until the garlic is fragrant and peas are bright green.
Reserve 0.25 cup of the pasta cooking water, then drain the pasta and add it directly to the skillet, tossing to coat in the pancetta fat.
Remove the skillet from the heat immediately and pour in the egg mixture, tossing constantly to create a creamy, emulsified sauce without scrambling the eggs.
Adjust the consistency with the reserved pasta water if needed, season with sea salt, and serve immediately.
