Cook rice according to directions.
Add rice to serving bowl
Return the saucepan to the heat with about 1/2” of water and bring up to a boil. Salt the water and stir in the asparagus and peas and cook for just about 1 minute, just long enough for them to brighten up and lose a bit of their bite.
Drain and run under cold water to stop the cooking, and add to the rice.
To the rice, asparagus, and peas add chives and 1/2 cup of the walnuts.
