Preheat oven to 400-degrees F (205 degrees Celsius).
Trim and cut the eggplant in half lengthwise. Place them (cut side up) on a baking sheet.
Drizzle the cut eggplant with 1 tablespoon olive oil and season with salt and pepper to taste.
Roast the eggplant in the preheated oven for 40 minutes (longer if using larger eggplants), until a fork pierces through the flesh easily. Remove and cool.
Meanwhile, drain a can of chickpeas (reserving the liquid) and place them in a blender.
When the eggplant is cool enough to handle scoop out the flesh from the skins (discarding the skins) and place in the blender with the drained chickpeas.
Add the tahini, 2 tablespoons of reserved chickpea liquid, 1 clove of minced garlic, 1½ teaspoon salt, and ½ teaspoon of black pepper to the blender.
Cover and blend until creamy, adding more chickpea liquid, if desired, to reach your preferred consistency.
Add to a bowl and drizzle with additional olive oil, and a sprinkling of sesame seeds before serving with dippers of your choice.
