Prepare the Chickpeas: Drain and rinse the chickpeas under cold water if using canned. If using dried chickpeas, cook them until soft.
Blend the Ingredients: In a food processor, combine the chickpeas, olive oil, garlic, lemon juice, cumin, and salt. Blend until smooth. If the mixture is too thick, add water a tablespoon at a time until you reach your desired consistency.
Taste and Adjust: Taste your hummus and add more salt or lemon juice if necessary.
Serve: Transfer the hummus to a serving bowl. Drizzle with olive oil, and garnish with parsley, paprika, or a sprinkle of cumin if desired. Serve with pita, veggies, or as a spread for sandwiches.
