First prepare the meatball mix. Place all the ingredients in a bowl and knead until stringy, for about 5-10 minutes. Keep in the fridge until shaping. You can add more or less spices if you choose to.
Cut off and discard the stem of the eggplant. Cut vertically into half and then cut to about 7 mm ( a little over ¼ inch) thick slices. Do not loose the sequence of the slices.
Then keeping the sequence of the slices place some meatball mix between each slice and place in a baking dish. Until all the material is finished.
Add the chopped tomatoes and peppers on the sides.
Mix the baking liquid mixture ingredients in a bowl and pour slowly on top of the eggplant and meatballs that are lined up.
Bake in a pre-heated oven at 200° Celsius (375°F) until the eggplants are ready. It will take about 50 minutes.
Half way through the baking take out the tray and using a spoon pour some of the stock on top of the meatballs to make sure they keep moist. Check, poking the smallest slices near the end, as that part cooks latest.
Let cool down for couple of minutes and serve.
