The primary ingredient used in hummus is chickpeas, also known as garbanzo beans. Chickpeas are blended with tahini, olive oil, garlic, lemon juice, and various seasonings to create this creamy and nutritious dip. Hummus is popular in Middle Eastern cuisine and has gained global recognition for its rich flavor and health benefits, including being high in protein and fiber. It can be served with pita bread, veggies, or used as a spread for sandwiches.
