This depends on the cooking time of the lentils, pulses and beans you are considering. For instance you can cook white rice and toor dal or moong dal together, but you cannot cook white rice and chickpeas or kidney beans together. As chickpeas and kidney beans have a cook time of 30 minutes, and white rice has a cook time of 6 minutes. But you can cook chickpeas and kidney beans along with brown rice, which has a cook time of 25 minutes.
