Searching for a recipe...

I'm housesitting for a friend on vacation right now, and she offered me some leftover couscous and dry red lentils. She's coming home tomorrow, and I want to cook them up for her as a "welcome home" dinner. For the life of me, I cannot find a recipe! Does anyone have a good (vegetarian) one that I could use? I also have some zucchini and carrot that I could add to it.
