In a large pot over medium heat, combine the olive oil and 1/3 of the pasta. Cook, stirring occasionally, until the pasta is crisp and dark browned, 10 to 12 minutes. Using a slotted spoon, transfer to a medium bowl and set aside.
To the oil remaining in the pot, add the chopped onion and cook while stirring for 3-4 minutes until translucent.
Add the chickpeas and bay leaf. Cook, stirring occasionally, until the chickpeas darken slightly and the bay leaf is toasted, 2-4 minutes.
Stir in the remaining pasta, 3/4 cup of chickpea liquid, 2 1/4 cups water, 2 tsp salt and 3/4 tsp pepper. Bring to a simmer over medium-high and cook, stirring occasionally, until the pasta is heated through and slightly softened, about 2 minutes.
Remove the pot from the heat, then remove and discard the bay leaf. Season with salt and pepper to taste.
Spoon pasta chickpea mixture into bowls, garnish with crispy fried pasta and chopped parsley.
