Onion Sambar

Vengaya sambar is what my dad used to call this. This is a nice combination with Puri or Chappati. It can be prepared real quick.
Ingredients :

• Gram Flour : 2 tbl spns
• Potatoes : 2 Nos. (optional)
• Onions : 1 No. Big
• Tomato : 1 No. 
• Green chillies : 3 Nos.
• Curry leaves : 1 string
• Mustard seeds : 1/2 tspn
• Urad Dhal : 1/2 tspn
• Turmeric : 1/4 tspn
• Cumin pwdr : 1/2 tspn
• Fennel seeds : 1/2 tspn
• Salt to taste 
• Oil : 1 tbspn

Method of preparation :

• Heat oil in a pan fry mustard seeds, urad dhal, fennel seeds, turmeric, green chillies and onions (chopped lengthwise) and fry when onions are almost done add tomatoes chopped  in big chunks
• In the meanwhile mix gram flour with some 2 cups of water in a bowl. 
• Add this mixture into the fried onions along with salt and cumin powder. 
• Add more water than the required thickness of the gravy as gram flour has to boil for 5 min during which it absorbs a lot of water. (Cooked potatoes to be added now)
• Do not add too much salt.  Cook for 5 min and serve hot with Poori or Chappati.

Note : This got to be served when its hot. Tends to thicken when its cold.  Add a lot of water and it thickens as gram flour cooks. I tried this with rice also and it tasted good.
