This is a reall quick and tasty accompaniment to food. It is a staple at our home, especially during summers.
Onions - 3 medium
Salt - 1 tsp
Vinegar - Enough to cover the onions
Chop the onions into chunks.
Add the salt.
Add vinegar to cover the onions completely.
Keep covered for a few hours. After a few hours, the onions will change their color.
Put it into an airtight container, put it in refrigerator. Enjoy!!
PS: I love these onions especially with dal chawal. If you cut these in rings, they work great in burgers/ sandwiches.
