Not sure -- are pink lentils the same as red? here's what I do to red lentils:
Chop an onion, sautee for a couple minutes until tender. Add lentils and required amount of water. Bring to a boil, add a tsp of ground turmeric and a tsp of corriander, and s+p to taste. Cook for 20 mins or until lentils are cooked through but not mooshy.
