Slice the eggplant in thick (1/2") slices, salt and pepper each side, drizzling with olive oil.
Bake at 400F for 10 minutes each side, set aside to cool.
Take the sliced potatoes and put in a microwave safe bowl, cover with water, add a hearty pinch of salt. Nuke for 7 minutes. Drain the water and set aside.
Melt the butter in a large frying pan and add the grated onion and garlic. Saute for about 2 minutes, until the onion has begun to turn clear.
Add the meat and begin to brown.
Add the spices and salt and pepper, wine and tomato puree.
Simmer for about 15-20 minutes until most of the moisture is gone.
Crack the 3 eggs into a bowl and whisk until well beaten. You'll use in a minute!
