Heat a pan adding all the ingredients under the list 'to temper' and saute till the mustard seeds sizzle. Then include onion, ginger and green chillies. Conitnue sauteeing.
When onion turns translucent, include chopped vegetables (I have used carrot, beans and green peas). Add 1.5 cups of water, salt and let the vegetables cook.
When the water boils, add the millet. Give a quick mix and keep it covered with lid. Let the millets cook in medium flame. It may take few minutes.
Once the millets get cooked completely, water would have been absorbed. Squeeze some lemon juice and garnish with grated coconut.
Amazingly healthy barnayard millet upma is ready to serve.
