Chop a small onion very fine. saute it (don't use olive oil), and then add curry powder OR a prepared curry paste. i usually use about 3-4 T
Of Patak's Kebab Paste. other spices are up to you. i usually add chili powder, cumin and coriander. add 2 cups of lentil, and water/stock (1:1 is good) to cover. simmer for an hour, add more liquid if necessary. adjust seasoning. then add 1 package offrozen spinach (fresh is ok, but frozen is convenient and just as tasty) and cook for about 10 more minutes.
It will also be a nice complement if you're eating a mostly liquid diet while recovering from surgery, if you get my drift.
