Simple Tomato koottu (Thakkali koottu)

Many may be very familiar with a side dish made with tomato. Just posting this for the new chefs and for my record.
This is one of the most simple but delicious dishes made by my mom. I always consider this koottu as my mom's signature dish. Though the version seems so simple, I have never achieved the mom's touch in this koottu.
Whenever my mom ran out of any vegetables in her fridge, then she used to make a simple dhal and this thakkali koottu along with rice. I always love these kind of quick to fix recipes, as they won't demand me to stay in the hot stove for long hours. Just a gentle serving on plain steamed rice can do the magic. Good for a lazy cook. huh:)
A very simple dish but surely a mouthwatering one.

The Vine tomato, Indian country tomatoes, cherry tomatoes or plum tomatoes add more taste to this koottu.
But the Bangalore tomato or Roma tomato won't bring the real flavor.
