This is how I make Khicri too with the exception of first putting water and haldi in the sauted onions+red whole mirch, and adding the presoaked rice and lentil once the water comes to boil. My family loves this khichri (which is called geeli as in wet khichri) as compared the sookhi as in dry khicri. The recipe of that khichri is more like any other pulav reipe or like what lusi has posted with masoor(orange) lentil.
With the geeli khichri we must must have green chutney, red chutney, achaar, lasi and butter/ghee. So it needs more effort then making a biryani lol
