First, peel and then chop the potatoes into 1/2 inch pieces. Cut carrots into rounds and also chop the beans into small pieces. Place all the veggies along with green peas on a steamer basket. Steam until they are cooked but not mushy. I used steaming basket and steamed in Instant for 2 minutes (with 1 cup water in main pot) and let the pressure release naturally. You can steam them using a stove-top steamer as well.
