In a food processor, combine the garlic, tahini, lime juice, oil, and salt. Process for 30 seconds. Scrape the mixture from the sides of the food processor. Add half of the chickpeas and process for 1 minute. Scrape the mixture from the sides and add the remaining chickpeas. If you prefer a thinner consistency, add the water as needed and blend well. Transfer the hummus to a bowl and serve with fresh vegetables. Cover and refrigerate any leftover hummus for up to 3 days.
