1. In a frying-pan heat 1 tbsp olive oil, and stir-fry the eggplants for about 5 to 6 min. Then pour another 1 tbsp olive oil over the eggplants and cook until wilted. Set aside.
2. In a bowl, add all the ingredient A and cooked eggplants (from step 1) and knead them well to combine evenly by hand.
3. Heat the vegetable oil in a fry pan, and shape the portion with your hands into a patty. Place the patty onto the pan over medium heat. Cook both sides until lightly browned. Then simmer (for about 15 mins) with a lid over gentle heat.
4. Transfer the burger to the plate. Wipe out the frying pan to get rid of any scorch mark and add all the sauce ingredient. Heat over medium-low heat and re-place the patties and coat with the sauce well.
