Mix 1 tbsp. oil, sugar and baking soda to the flour. Now divide into three equal portions. To one portion, add the spinach puree and knead into a dough. Add water if required. Keep aside. To the second portion, add the beetroot puree and knead into a dough with required quantity of water. Keep aside. Knead the remaining flour with enough water and keep aside for 10-15 minutes. Roll all the three dough separately into a big circle, just like chapatti by dusting some flour.
