Use a thick bottomed deep pot or pan. Follow the recipe and after adding moong beans, add 3.5 cups of water. Cover the pot with a lid and cook the beans on a medium heat, stirring occasionally, until the lentils are tender. Add a bit of water if necessary as the lentils cook. Tip: It's best to soak the beans overnight, if cooking them in a pot or pan, so that they quick faster.
