Heat oil in a pan, add mustard seed and cumin. Fry for few minutes till the seeds pop. You might want to close the pan with a lid so that the seeds will not pop out of the pan. Add the rest of the ingredients except the chickpeas and fry till the onions are gold brown. Finally add the chickpeas, add salt taste. Fry for another 2-3 minutes. Serve hot. * these items are optional. If sliced coconut is hard to come by substitute with unsweetened coconut flakes.
