In a small saucepan, saute onion and carrot in oil until tender. Add rice and quinoa; stir to coat. Stir in broth and pepper.
Bring to a boil. Reduce heat; cover and simmer for 15-20 minutes or until liquid is absorbed, adding the broccoli during the last 3 minutes of cooking. Remove from the heat; let stand for 5 minutes. Fluff with a fork.
