Heat a frying pan on medium heat and add the vegetable oil.
Peel the aubergines - eggplants in stripes and slice them ½ " (1 cm) thick.
When the oil is hot, fry the aubergines - eggplants for 2-3 minutes on both sides until lightly browned and slightly softened. Do it in batches and add more oil if needed.
Place the aubergines - eggplants onto a colander to drain the excess oil.
When you finish frying all the aubergines - eggplants, use the same pan to prepare the meat sauce.
To make the meat sauce, add the ground meat to the pan and place it on medium heat.
Cook the meat until brown, and it releases its fat, stirring occasionally to break the ground meat down into small pieces.
Add onions, peppers, chili, and garlic, sauté until translucent then add freshly ground black pepper, cumin and salt. Sauté for 30 more seconds.
Stir in the tomato paste and cook for a minute then add the chopped tomatoes.
Add the stock and chickpeas, stir well and cook on low heat for 10 minutes.
Take the pan off the heat and add chopped parsley.
Preheat the fan oven to 180° C (360° F).
To assemble the moussaka, layer half of the aubergines - eggplants on the bottom of an oven dish size 22 cm-24 cm (9" - 10") diameter and then sprinkle some salt.
Spoon half of the meat mixture on the aubergines - eggplants and spread evenly on top.
Layer the rest of the aubergines - eggplants on the meat filling and sprinkle some more salt before topping them up with the rest of the meat filling.
Cover the dish with tin foil or a lid and put it in the hot oven. Cook for 1 hour then remove the lid/tin foil and cook for another 45 minutes or until the aubergines - eggplants are softened and the sauce has thickened.
