Bake: Preheat oven to 400°F. Slice eggplant into ¼ inch thick rounds and set on a parchment paper-lined baking sheet. Brush with olive oil, then bake for 20 to 30 minutes, or until soft, flipping eggplant over halfway through cooking.
Puree: Peel away the skin of the eggplant and add the flesh to a food processor, along with the garlic, lemon, drained chickpeas, tahini, paprika, salt, and pepper. Puree until smooth, taste, and add more seasonings to suit your taste.
