This is a fast little wholesome dish. Just add a green salad and slice of French bread.
Start a large pot of lightly salted water to boil for pasta. Heat the oil or vegetable broth in a large skillet over medium heat and add onion, garlic and red pepper flakes. Cook until tender and then add the chickpeas, and parsley, with salt and pepper to taste. Add the liquid from the chickpeas and turn heat down to simmer. Add pasta to water and cook al dente, according to package instructions. Right before it is done, scoop up and set aside one cup of the pasta water to use later. Add cherry tomatoes to sauce. Drain pasta and toss with the sauce. Add part of the pasta water if sauce is too thick. Check for salt and pepper. Serve in warm bowls.
