Bombay chutney /Quick easy gravy for chappathi

My mom learnt this recipe from her sister who lives in Bombay. It is a very simple gravy that tastes good with chappathi.

Onion - 1 medium sized

tomato - 3 riped ones

green chilli - 2

red chilli - 1

besan - 2 tbsp

curry leaves

corriander

mustard

turmeric

salt

First in a pan heat little oil and add mustard, when it splutters add jeera then add chillies, curry leaves, add onions and saute it well. Then add cut tomatoes and add tumeric. Then in a cup, mix besan with water and bring it to nice watery consistency and then add it to the pan and let it boil well so that the raw smell of besan goes out. Add water as required and garnish it with coriander leaves.
