Heat oil in a medium saucepan over medium heat. Add crushed garlic; sauté 1 minute. Add salt, pepper, chickpeas, and broth; bring to a boil. Cover, reduce heat, and simmer 15 minutes.
While garlic mixture simmers, cook pasta in boiling water 9 minutes, omitting salt and fat; drain well.
Place chickpea mixture in a food processor, and process until smooth. Combine chickpea mixture, pasta, tomatoes, minced garlic, fresh parsley, and lemon juice; toss well. Sprinkle with cheese. Serve immediately.
