Preheat the oven to 425ºF and line a baking sheet with parchment paper. Place the eggplant on the sheet, cut side facing up and brush with half the vegetable broth.
Lightly dry the chickpeas with paper towel and add to a medium-sized bowl. Toss with half the cumin, garlic, and onion powder. Add the chickpeas to the baking sheet alongside the eggplant. Bake for 15 minutes. Remove, gently shake the baking sheet and flip the eggplant. Bake for 15 minutes more.
Make the tahini dressing by adding the remaining vegetable broth, tahini and lemon juice to a mason jar. Shake vigorously until all ingredients are combined. If the dressing is too thick, thin with a splash of water.
Once the eggplant and chickpeas are finished cooking, add to a plate. Top with tahini dressing and parsley. Serve and enjoy!
