Wash and cut the cucumber into one inch pieces. Let them be of the same size.
Take oil in a pan, add mustard seeds, as it splutters, put the turmeric powder and asafoetida. Throw in the cucumber pieces.
I usually close a lid with some water over it, this helps in even cooking. Alternatively, you can sprinkle a little water over the vegetable and close the lid.
Cook them till tender, avoid adding salt in the beginning.
Once the cucumber slices are cooked, put salt, spice mix and a little chilli powder.
Mix it and let it cook for sometime.
Cucumber Stir Fry is ready to serve.
