A wedding feast or a festive feast in our family is incomplete without aviyal. Aviyal is a medley of native vegetables & tubers cooked in coconut gravy. Traditional Indian recipes like kummiyanam, adai, avial, panchamirtham, etc. use assorted grains, pulses, vegetables, or fruits. But nowadays we could find the nutritionists recommending us to include a medley of  vegetables, pulses, grains, or fruits in our diet regularly as it prevents vitamin & mineral deficiency. Hence it is a good practice to prepare such foods often and serve them particularly to growing children and old people.
