Turn on the grill (or just do the entire process on the tawa/griddle on stove)
Roll the eggplant pieces in the prepared dressing and leave it in the bowl until the grill is ready
Put the eggplant pieces on the grill and let stand for 30 seconds. Then cover and grill for 2-3 minutes.
Meanwhile add the chopped tomatoes and peppers into the remaining dressing/marinate mix and keep it aside
Flip over the eggplant pieces and continue grilling for another 2 minutes. Then remove and keep aside
Now add the tomato-pepper mixture on the grill and add all the remaining sauce over it.
Grill similarly for 2-3 minutes on each side. While flipping over take some of the collected sauce out of the grill and pour it back on the grill.
Save the collected-drained sauce while grilling to apply on the tortilla as dressing!
