Aloo Vankaya Curry

I came very late to home and was so hungry. I wanted to make something real quick, tasty and less spicy and ofcourse with less oil. Here is the recipe that I tried and came out really good. I enjoyed my dinner with phulkas. This can go well with hot rice too. Here you go:
Ingredients:
Aloo or White Potatoes – 2
Vankaya or Brinjal –3
Ginger – Half inch piece, sliced very thin pieces
Tomatoes – 1 (sliced into small pieces)
Onion – 1 small piece (1/4th of a big onion)
Coriander Powder – 1 spoon
Oil – 2 spoon
Turmeric – a pinch
Red chilli powder – 1 spoon (As per taste)
For Seasoning or Tadka or Popu:
Chana dal – ½ tsps
Urad Dal – ½ tsps
Mustard Seeds – ½ tsps
Jeera seeds – ½ tsps
Curry leaves – 2 to 3

Recipe:
Take a bowl of water, put some salt in it. Cut the brinjals into 4 pieces and put in salt water. Peel the potatoes and cut into small cubes. Take a pan, heat the oil. Add Chana Dal, Urad Dal, jeera seeds and mustard seeds for Tadka and let it turn golden brown. Add curry leaves and Onions, and sliced Ginger pieces. let it turn brown. Add brinjal and potatoes (without water) and add salt, turmeric into it. Mix well, close the lid and cook on medium heat for 10 mins. Add a small glass of water, and coriander powder, red chilli powder, and sliced tomato. Mix well and cook for 10 more mins. This will be good with Roti or Hot rice.
