I have posted it earlier also but that was with onion. This dish is without onion. Of course rest of the recipe is same. A very easy and tasty dish. It can consumed with rice or roti also.

Ingredients:

Tomatoes - 6 to 8 Medium Sized
Green Chillies - 2
Salt - to taste
Turmeric Powder - 1 tsp
Red Chilli Powder - 1 tbsp
Pigeon Peas/Toor Dal - 1 cup
Curry Leaves - 5 to 7
Coriander Leaves - fist full

For Tadka:

Oil - 1 tbsp
Mustard Seeds - 1/2 tbsp
Cumin Seeds - 1/2 tbsp
Red Chillies- 1
Asafoetida - 1 tsp

Procedure:

Pressure cook the dal for two whistles. (For one cup of dal add only one cup of water). Keep it aside.
Cut each tomato into four parts.
Heat oil in a thick bottomed vessel. Add all the ingredients under 'For Tadka'.
Once they start spluttering add tomatoes and green chillies.
Just make green chillies into two halves.
Add salt and turmeric powder.
Cover it and allow the tomatoes to cook completely. Stir occasionally.
Once the tomatoes cooked, add the dal. Drain the excess water in the dal, if any, and do not mash it. Mix well.
Add red chilli powder to it and mix well.
Serve tomato pappu with rice or roti. The best accompaniment to it are dry chillies or majjiga mirapakayalu.
