My Mother taught me this.. its really quick and requires very less ingredients. Try it..
Ingredients
2 Onion medium (sliced)
1½ tsp Red chilly powder
Salt (as per taste)
Oil (for frying onions)
Method
2 med sized onions – Sliced
Oil for frying onions
1 1/2 tsp Red chilly powder (Depends on how hot you want it to be)
Salt to taste
Heat oil in a pan. Keep the fire on high Add the onions and fry till it is brown. Remove from fire. Add chilly powder and salt. Mix well and let it cool for a while. Grind it in a blender - to a not so fine paste.
It goes really well with Dosas or Idlis. In case you are bored of grating coconut or you don't have time!
