First, bake sweet potatoes on 350F (175C) for about 30 minutes until soft. Once baked, combine the 2 cups of sweet potatoes, 1 can rinsed chickpeas, 1/4 cup tahini sauce, 2 tablespoons lemon juice, 2 garlic cloves (or garlic powder), and 1/2 teaspoon salt in a food processor. Blend until smooth. Add a little water if needed to reach your desired consistency. Enjoy it with your favorite veggies or crackers.
