Heat 2 tablespoons of olive oil in a large heavy-bottomed pot over medium heat.
Add the cubed eggplant and sauté for 8-10 minutes until golden brown and softened. Remove the eggplant from the pot and set aside on a plate.
In the same pot, add the remaining 1 tablespoon of olive oil. Add the chopped onion and minced garlic, cooking for 4 minutes until the onions become translucent.
Add the ground beef, breaking it apart with a wooden spoon. Cook until fully browned and no pink remains, about 6-8 minutes. Drain any excess fat if desired.
Stir in the ground cumin, ground cinnamon, salt, and black pepper. Cook for 1 minute until highly fragrant.
Pour in the crushed tomatoes and the rinsed chickpeas. Stir well to combine, scraping any browned bits from the bottom of the pot.
Return the cooked eggplant to the pot. Bring the stew to a gentle boil, then immediately reduce the heat to low. Cover and simmer for 20-25 minutes to allow the flavors to meld.
Remove the pot from the heat. Stir in the fresh lemon juice.
Garnish with chopped fresh parsley. Serve hot alongside warm pita bread and a side of yogurt.
