In a large pot, saute the onions and garlic in olive oil for about 2 minutes over medium heat. I use pre-minced garlic to save me time!
Next, add all of the remaining ingredients except for the vodka, chickpeas, and parsley and stir to combine. Cover it and bring it to a boil.
Once it's boiling, lower the heat and simmer for about 10 minutes, stirring occasionally.
Add the vodka, chickpeas, and parsley. Continue cooking, uncovered, until the pasta is al dente, about 8 more minutes.
Notes
This pasta is best when served right away so that it can maintain its creamy texture. If you are reheating it later, I would suggest adding some olive oil to the pasta after reheating and then mixing it around to achieve a somewhat creamy texture again.
