My grandson's fiancé, Merve, whose ethnic background is Turkish has introduced him to Turkish food.  This recipe which they got from allrecipes.com is one they make often.  It's very tasty and nutritious as well as flexible.  My grandson, Ohan, has made some notations.  For example, when he accidentally skipped the tomato paste, he added a whole can of tomatoes to compensate.  Also, he notes it often comes out very thick and thickens upon sitting, in each case just add water to get it to the desired consistency.
