You can prepare the peas in advance and either refrigerate up to a day or set aside for use later the same day. By preparing the rice separately, it reduces the starchiness of the soup. You may use your favorite type of rice and the correct amount of liquid to prepare according to package instructions and store with the peas. The jalapeños are optional, but will add a little bit of spice to the soup. Just be sure to remove them at the end!
