Fill a pan with water.
Take all the ingredients in a bowl and place it in the pan. Make sure the water doesn't enter the vegetables.
Put the pan on the stove and close the lid.
Steam the vegetables till they are completely cooked and soft.
Let the cooked vegetables cool a little. Grind them to a puree.
Add a little cumin/jeera powder for taste. You can also add breast milk or formula to think it out.
