Here is what you need to do in order to prepare this Vegetable Pulao in an Instapot. First chop all the veggies that you plan on adding to this rice dish. Wash and soak basmati rice in water for 30 minutes. Soak mixed nuts (cashews+almonds+pistachios) in water for 10 minutes. Drain the water and transfer the nuts to a blender along with ginger, garlic and green chillies. Blitz to a smooth paste. Keep it aside. Now connect the Instapot to the power outlet. Click the 'saute' button and add oil to the pan. If you are not vegan then you can add ghee instead. Once you know its hot enough, add and temper cumin seeds. Then add the ground paste to the pot and using a wooden spoon, fry the masala for 2 minutes. Then add the whole garam masala like peppercorns, cloves, bay leaf, cinnamon and star anise. Fry for 30 more seconds. Then add sliced onions and continue to saute till they turn translucent. Now add the chopped veggies (cauliflower,green beans, carrots, potatoes and green peas) one by one. No need to wait for each vegetable to cook. You can just add them all in together. I would recommend using fresh veggies as much as possible. But you may use frozen veggies as well.
